I think the length of pool in inches is actually 12*12=144 because there are 12 inches in a foot.
Also, the scale factor would be 144/16 = 9.
Answer:

Step-by-step explanation:
step 1
Find the equation of the function g(x)
Let
A(0,-2) and B(5,0)
Find the slope m

Find the equation of the line into slope intercept form

we have

substitute

step 2
Find the inverse of g(x)
Let
y=g(x)

Exchange the variables, x for y and y for x

Isolate the variable y
Multiply by 5 both sides to remove the fraction



Let

so

A.
The dotted line means that y has to be strictly less than 1.
The solid line means that y=x are also solutions giving y more than or equals to x.
As image or option not given,
First let me explain the meaning of term Reflectional symmetry :
If you divide an object or image in such a way , that the two parts of that image looks symmetrical or mirror images of each other.This phenomenon is described as reflectional symmetry.For example , if you cut human body vertically , the two parts are mirror images of each other.In geometrical shapes, if you cut a square along it's diagonals, or through line joining mid points of sides of square , you get mirror images of square.In Capital Alphabets , Like in A, Vertical line through Vertex Describes it's reflectional symmetry.
Reflectional symmetry for letter T= Vertical line shown in picture below.
