I have my notes here that will help you in answering the problem:
Test to determine if a function y=f(x) is even, odd or neither: Replace x with -x and compare the result to f(x). If f(-x) = f(x), the function is even. If f(-x) = - f(x), the function<span>is odd.

I hope my answer has come to your help. God bless and have a nice day ahead!
Can you add a picture? I don't see a circle. I will answer this question if you add a picture.
g(x) is the inverse of f(x)


Here it is given that the width is x ft and total length of the fence is 2400 ft .
Let the length be y ft
So we have

Let A represents area, and area is the product of length and width .
So we get

Substituting the value of y, we will get

Second part
The area is maximum at the vertex, and vertex is

And

And that's the required dimensions .
Compatible numbers are easy to divide mentally.
hope this helped
