Answer:
The function displayed in the table is best described as an Exponential Decay Function.
Step-by-step explanation:
First, the main difference between a linear and an exponential function is the shape of its graph, as well as the presence of either a constant ratio or a constant rate of change.
Linear functions are functions with a base function of [tex]f(x)=mx+b[/tex], which has a constant rate of change ([tex]m[/tex]), and the shape of its graph will be a straight line.
Exponential functions on the other hand use the base function [tex]f(x)=a^x[/tex], where [tex]a[/tex] is the constant ratio of the function, and its graph is curved and has a horizontal asymptote that the graph will approach but never touch as it either increases or decreases to positive or negative infinity respectively.
The function in the problem gives you four points that are on its graph: (-2, 540), (-1, 270), (0, 135), and (1, 67.5). Using these points, you can determine whether it is a linear or exponential function. You can tell that when the x-value increases by 1, the f(x) value is divided by 2, or multiplied by [tex]\frac{1}{2}[/tex]. Since there is a constant ratio instead of a constant rate of change in the function, you would know that the function in the table is an exponential function. Since the function is also constantly decreasing, the function would be best described as an Exponential Decay Function.

Step-by-step explanation:
Write each function in vertex form and identify the vertex.
f(x) = x^2- 16 x + 3
f(x) = 4x^2+24x-7
f(x) = -2x^2- 8x + 9
For the quadratic equations -
1) f(x) = x² - 16x + 3 → Vertex form is y = 3(x - 8)² - 61 and vertex is (8,-61).
2) f(x) = 4x² + 24x - 7 → Vertex form is y = 4(x + 3)² - 43 and vertex is (-3,-43).
3) f(x) = -2x² - 8x + 9 → Vertex form is y = -2(x + 2)² + 17 and vertex is (-2,17).
What is a quadratic function?
A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.
The quadratic equation is written in the form ax² + bx + c = 0.
The vertex form of a quadratic equation is -
y = a(x - h)² + k
The first equation is - f(x) = x² - 16x + 3.
Here, a = 1, b = -16 and c = 3
The formula for h is -
h = -b/2a
h = -(-16)/2(1)
h = 16/2
h = 8
The formula for k is -
k = c - (b²/4a)
k = 3 - [(-16)²/4(1)]
k = 3 - (256/4)
k = 3 - 64
k = -61
So, the vertex form is -
y = a(x - h)² + k
y = 3(x - 8)² - 61
The vertex is written as (h,k).
The vertex is (8,-61).
Therefore, the vertex form and vertex is y = 3(x - 8)² - 61 and (8,-61) respectively.
The second equation is - f(x) = 4x² + 24x - 7.
Here, a = 4, b = 24 and c = -7
The formula for h is -
h = -b/2a
h = -(24)/2(4)
h = -24/8
h = -3
The formula for k is -
k = c - (b²/4a)
k = -7 - [(24)²/4(4)]
k = -7 - (576/16)
k = -7 - 36
k = -43
So, the vertex form is -
y = a(x - h)² + k
y = 4(x + 3)² - 43
The vertex is written as (h,k).
The vertex is (-3,-43).
Therefore, the vertex form and vertex is y = 4(x + 3)² - 43 and (-3,-43) respectively.
The third equation is - f(x) = -2x² - 8x + 9.
Here, a = -2, b = -8 and c = 9
The formula for h is -
h = -b/2a
h = -(-8)/2(-2)
h = 8/-4
h = -2
The formula for k is -
k = c - (b²/4a)
k = 9 - [(-8)²/4(-2)]
k = 9 - (64/-8)
k = 9 + 8
k = 17
So, the vertex form is -
y = a(x - h)² + k
y = -2(x + 2)² + 17
The vertex is written as (h,k).
The vertex is (-2,17).
Therefore, the vertex form and vertex is y = -2(x + 2)² + 17 and (-2,17) respectively.

The y-coordinate for the solution to the system of equations is -3.
What is a system of equations?
A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations. The intersection of two lines represents the system of equations' solution.
Given system of equations are,
6x + 11y = -3
4x + y = 17
To solve these equations, we must first remove x or y terms.
To do this we must make the removing term's coefficients the same.
In this case, let's remove y.
We are multiplying the second equation by 11. Then,
6x + 11y = -3
44x + 11y = 187
Now we will subtract the second equation from the first.
- 38x = -190
x = 5
Now to find y, substitute x in any one of the equations.
6 * 5 + 11y = -3
11y = -33
y = -3
Hence the y-coordinate for the solution to the system of equations is -3.

The total amount due on November 15th would be $1667.81
Let's first calculate the trade discount amount:
Suggested list price: $1400
Trade discount rate: 40/10 = 4%
Trade discount amount: $1400 x 4% = $56
After deducting the trade discount, the price becomes:
$1400 - $56 = $1344
Next, let's calculate the cash discount:
Amount after trade discount: $1344
Cash discount rate: 8/10 = 8%
Cash discount amount: $1344 x 8% = $107.52
After deducting the cash discount, the price becomes:

The cumulative relative frequency graph shows that
The slope between 0 and 4 is substantially steeper than the curve between 6 and 14.
Then
Because most of the data values are between 0 and 4 (where the histogram's highest bar appears) and relatively few values lie between 6 and 14 the histogram's distribution should be skewed to the right, resulting in low bars tailing to the right side of the highest bars.
