The requried, inverse of a function is a function for which the values or the domain and the range are interchanged. Option C is correct.

The inverse of a function is a new function that results from interchanging the input (domain) and output (range) of the original function.

Here,
if f(x) is a function, its inverse function is denoted by f⁻¹(x), and it is defined such that f⁻¹(y) = x, where y = f(x) is the original function.

For example, if f(x) = 2x + 3, the inverse function f⁻¹(x) is found by interchanging x and y, and solving for y:

x = 2y + 3

2y = x - 3

y = (x - 3)/2

Therefore, f⁻¹(x) = (x - 3)/2, and it is the inverse of the original function f(x). Note that the domain and range of the inverse function are interchanged with respect to the original function.

Lourdes will spend an amount of  $1.50 more if she buys only 3-packs of paper.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

If Lourdes buys only 3-packs of paper, she will need to buy 12 / 3 = 4 sets of paper.

At $10.50 per set, this will cost her 4 x $10.50 = $42.

If Lourdes buys only 4-packs of paper, she will need to buy 12 / 4 = 3 sets of paper.

At $13.50 per set, this will cost her 3 x $13.50 = $40.50.

So, Lourdes will spend $42 - $40.50 = $1.50 more if she buys only 3-packs of paper.

The function can be used to model the exponential growth or decay that occurs in real-life situations that fit this particular pattern is y = 4(-0.4)ˣ + -4

An exponential function is a mathematical function that has the form

=> y = abˣ,

where a is a constant and b is the base of the exponential.

To start, we will use the first point, (1, -1.6), to write an equation that relates x and y. Let's call the constant a in our exponential function "k". Using the point (1, -1.6), we can write the equation:

=> -1.6 = k * b¹

Next, we will use the second point, (2, -0.64), to write another equation that relates x and y. Using the point (2, -0.64), we can write the equation:

=> -0.64 = k * b²

Now that we have two equations, we can solve for the two unknowns, k and b, by dividing the two equations:

=> (-0.64) / (-1.6) = k * b² / k * b¹

b = (0.64 / -1.6)¹

b = -0.4

With b determined, we can substitute it back into one of the equations and solve for k:

=> -1.6 = k * (-0.4)¹

=> k = -1.6 / (-0.4)

=> k = 4

So our exponential function that passes through the points (1, -1.6) and (2, -0.64) and has a y-intercept of -4 is:

y = 4 * (-0.4)ˣ + -4

Kelly can run 1/2 mile in 3 minutes. 1/6 mile Kelly run in 1 minute if he runs at the same pace the entire time.

The word "mile" is derived from the Latin "mille passus," which means "one thousand paces." The English Parliament established the Mile at eight furlongs (one furlong is 660 feet) in 1592. A mile is a unit of measurement that is standardised as exactly 1609.344 metres by the International agreement in 1959. A mile is exactly equivalent to 5280 feet, or 1760 yards.

Kelly can run 1/2 mile in 3 minutes so the ratio is 1/2 mile per 3 minutes

For transforming 3 to 1 we need to divide by 3 because we have to keep the ratio value, we have to divide also the numerator by 3 :

Case 3: f(x) = √x - 3 (Correct choice: A)

Case 4: f(x) = √(x - 4) - 4 (Correct choice: A)

In this problem we find four cases of functions that must be transformed by rigid transformations. Rigid transformations are transformations applied on functions such that its features are not altered. We should apply, if possible, the following rigid transformations:

Reflection across the y-axis

f(x) → f(- x)

Translation to the right

f(x) → f(x - k), where k > 0

Translation downward

f(x) → f(x) - k, where k > 0

Now we proceed to determine the image of each function:

Case 1

f(x) = √x

Reflection across the y-axis

f(x) = √(- x)

Case 2

Translation 4 units right

f(x) = √(x - 4)

Case 3

Translation 3 units down

f(x) = √x - 3

Case 4

Each person will get 1 [tex]\frac{7}{9}[/tex] cups of ice cream.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

Given that, Brian is splitting 4 quarts of ice cream with members of the team.

Assume the number of members of the team = 9

We have to find how many cups each member gets.

First we have to convert the measurement quarts to cups.

1 quart = 2 pints

1 pint = 2 cups

1 quart = 2 × 2 cups = 4 cups

We have 4 quarts of ice cream.

4 quarts = 4 × 4 = 16 cups

Number of cups each member gets = 16/9 cups = 1 [tex]\frac{7}{9}[/tex] cups

Hence there will be 1 [tex]\frac{7}{9}[/tex] cups for each member.

Answer: To find the inverse of the function f(x), we need to switch the roles of x and y, so that x becomes the dependent variable and y becomes the independent variable. Then, we need to solve for x in terms of y.

Let y = √x - 5, then x = y^2 + 5.

To find f^-1(2), we need to substitute 2 for y in the equation x = y^2 + 5:

x = 2^2 + 5 = 9

So f^-1(2) = 9.

This means that the inverse of f(x) at 2 is 9. In other words, if f(x) = 2, then x = 9.

Using percentages we know that the rate of commission of the salesperson based on the net sales is 15.5%.

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and sometimes "pc" is also used, the percent symbol, "%," is frequently used to indicate it.

A % is a number without boundaries and without a standard measurement.

So, calculate as follows:

5880/100 * 11.5 = 676.2

Now,

5880 - 676.2 = 5,203.8

Now, calculate the percentage as follows:

806.59/5,203.8 * 100

15.5%

The intersection points are (6, 6) and (-6, -6).

What is Intersection points?

The point at which two lines or curves intersect is referred to as the point of intersection. The point at which two curves intersect is crucial because it is the point at which the two curves take on the same value.

The given curves are the polar equations of two circles with radii 6. To find their intersection points, we can set the two equations equal to each other and solve for Ф.

6 sin(Ф) = 6 cos(Ф)

Dividing both sides by 6 and rearranging terms, we get:

tan(Ф) = 1

This equation has infinitely many solutions, but we are only interested in those that lie in the interval [0, π/2].

Ф = π/4 satisfies this condition and corresponds to the point (6, 6) in Cartesian coordinates.

Since the two curves are circles, they are symmetrical about the origin. Therefore, we can deduce that the other intersection point is (-6, -6).

Therefore, the intersection points are (6, 6) and (-6, -6).
