In essence, a function is a rule that assigns to each value of the input set (also known as the domain), a unique value of the output set (also known as the range).

A function is a fundamental mathematical concept that is used to describe the relationship between two sets of values.

To understand the idea of a function, imagine a machine that takes in an input and produces an output. The input values are the domain of the function, and the output values are the range. A function can be represented as an equation, a graph, or a table. For example, the equation f(x) = x + 3 represents a function that takes in an input value x and produces an output value that is 3 greater than the input value.

One of the key features of a function is that each input value must have a unique output value. This means that if you input the same value into the function twice, you should get the same output value both times. In mathematical terms, we say that a function is well-defined if it has a unique output value for each input value.

Functions are used in a wide range of mathematical applications, from algebra and calculus to statistics and data analysis. They provide a powerful tool for describing and analyzing relationships between different sets of values.

Answer:

Step-by-step explanation:

If we subtract 2 from 52 we get 50 and ten mutiplys into 50.

The mean is 11.25 and median is 8, and from the employees' perspective, the median would be a better measure of central tendency to use for determining the raise cut-off point.

{1, 4, 5, 6, 7, 9, 9, 11, 15, 18, 27, 32}

The mean is the average value of the dataset. We can find the mean by summing up all the values and dividing by the total number of values:

mean = (1 + 4 + 5 + 6 + 7 + 9 + 9 + 11 + 15 + 18 + 27 + 32) / 12

= 135 / 12

= 11.25

Therefore, the mean of the dataset is 11.25.

The median is the middle value in the dataset. If the dataset has an odd number of values, the median is the middle value. If the dataset has an even number of values, the median is the average of the two middle values.

In this case, the dataset has 12 values, so we need to find the average of the 6th and 7th values:

median = (7 + 9) / 2

= 8

Therefore, the median of the dataset is 8.

From the employees' perspective, the median would be a better measure of central tendency to use for determining the raise cutoff point. This is because the median is not affected by outliers as much as the mean.

In this dataset, the value of 32 is much larger than the other values and could skew the mean upward, which would result in a higher cutoff point for the raise. On the other hand, the median is not affected by the outlier and provides a better representation of the central value of the dataset.

A 5% raise for employees who have been employed for at least 8 years (the median) would be more fair and reasonable for all employees.

Let the number of minutes be m.

Let the total cost be T.

Given the following data:

Cost of air conditioner = $130

Running cost = $0.25 per minute

Time = 400 minutes.

To write a function that models the total cost of running the air conditioner for the first 400 minutes:

How to solve a word problem.

First of all, we would write an equation to models the total cost of running the air conditioner for the first 400 minutes:

0.25m

For the total cost:

T= 130 + 0.25m

For the domain:

The value of m is the domain and it can be chosen from 0 to 130.

Domain (m) = [0, 130].

For the range:

A range represents the minimum and maximum value of a data set.

Thus, the value of T would be between 130 and 230.

Range = [130, 230].

Answer:

 44 ft

Step-by-step explanation:

You want to know the height of a tree whose top is at angles of elevation of 42° and 50° from points 12 feet apart.

The tangent of an angle is related to the side lengths of a right triangle by ...

  Tan = Opposite/Adjacent

This tells us the length of the side adjacent to the angle of elevation is ...

  Adjacent = Opposite/Tan

Here, the height of the tree is the side of the triangle opposite the angle of elevation, and the difference of adjacent sides is 12 ft:

  12 = h/tan(42°) -h/tan(50°)

  h = 12/(1/tan(42°) -1/tan(50°)) ≈ 12/(1.11061 -0.83910) ≈ 44.197

The approximate height of the tree is 44 feet.

c ?

To find the height of flagpole c, we can use the proportionate ratio as:

a = (x + y)

c        y

16.5 = (12 + 10)

 c            10

16.5 / c = 22 / 10

The solution is Option A.

The transformed equation is y = -x - 8

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the parent function be represented as A

Now , the value of A is

f ( x ) = x or y = x

Now , when the function is reflected over the y-axis , the x coordinate of the function is changed to its additive inverse

So , reflected function is g ( x ) = -x

Now , when the function is translated down 8 units ,

It is a vertical shift of down by d units: y = f(x) - d

Answer:

Step-by-step explanation:

If k=1 is a zero of f(x), then (x-1) is a factor of f(x) by the factor theorem. We can use polynomial long division or synthetic division to find the quotient when f(x) is divided by (x-1):

2 -3 -5 6

1| 2 -1 -6

2 -3 0

The quotient is 2x^2 - 3x, so we can write f(x) as:

f(x) = (x-1)(2x^2 - 3x) = (x-1)x(2x-3)

Therefore, the correct answer is B) f(x) = (x-1)(x+2)(2x-3).

Answer:

To show that (x-3) is a factor of the polynomial h(x) = f(x) - f(3), we need to use the definition of a polynomial factor. A polynomial factor is a polynomial that, when multiplied by another polynomial, results in the original polynomial.

First, let's evaluate f(3) to find the value of h(3).

h(3) = f(3) - f(3) = 0

Now let's examine the value of h(x) for any x other than 3.

h(x) = f(x) - f(3)

If (x-3) is a factor of h(x), then for any value of x other than 3, h(x) should be equal to zero.

So,

h(x) = (x-3)g(x)

where g(x) is another polynomial.

Therefore, by definition, (x-3) is a factor of h(x) = f(x) - f(3).
