Answer:
-3
Step-by-step explanation:
A. Let us assume the width of the pool = x
Then
Length of the pool = 3x + 3
Depth of the pool = 2(3x + 3) - 7
= 6x + 6 - 7
= 6x - 1
B. Area of the land space = Width * length
= x * (3x + 3)
= 3x^2 + 3x
C. Volume of the pool = (6x - 1) * (3x^2 + 3x)
= 18x^3 + 18x^2 - 3x^2 - 3x
= 18x^3 + 15x^2 - 3x
D. The highest degree is actually 3 and the number of terms that we get is also 3.
This is a linear function. They vary directly with each other.
x increasing by 1 each time.
y increases by 4 each time.
I hope this helps!

For future reference, you could use Desmos for graphs. but should be (1,1)
