Function 1:
For the given table

you can plot the graph of the function (see first attached diagram). This function is linear and has equation f(x)=3x+4.
Function 2:
For the given function f(x)=-2x+3 you can create a table

and plot the graph (see second attached diagram).
Function 3:
For the given graph of the function, you can find the function:

Thus, the equation of the function 3 is

Answer:
6000 in³
Step-by-step explanation:
To solve this problem, we simply have to find the volume of the shipping container that will be just enough to contain the 20 soda boxes.
To do this, we find the volume of each soda box and multiply it by the total number of soda boxes held by the shipping container.
Volume of the box = L * B * H
L = length = 15 in
B = breadth = 4 in
H = height = 5 in
V = 15 * 4 * 5 = 300 in³
This is the volume of each soda box.
The volume of 20 soda boxes will then be:
V = 20 * 300 = 6000 in³
This is the volume of 20 soda boxes and hence, the minimum size the shipping container can be.
Simplify. Distribute 7 to all terms within the parenthesis
7(x) = 7x
7(-4) = -28
7x - 28 is your answer

The slope is the change in Y over the change in X.
Slope = (0 - 1) / 4-2)
= -1/2
The slope is -1/2
