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!

If we put the parabola in a coordinate system with vertex at the origin and facing the positive x axis. We have the following points lying on the curve:
(4, 8), (4, -8)
For parabola facing right:
y2 = 4ax
Substituting either coordinates to solve for a:
a = 4
Therefore, the microphone should be placed 4 inches from the bottom of the disk.

Step-by-step explanation:
Remark
Notice you are working with minus signs. You final answer must be "smaller" than what you started out with. In other words, your final answer must be more negative.
Givens
Beginning level below sea level = -1260 feet
rate of descent = 5 feet per minute
Number of minutes = 12 minutes
Equation
Final level = initial level - rate * time Substitute givens into equation.
Solution
Final Level = - 1260 - 5*12
Final Level = - 1260 - 60
Final level = - 1329
Answer: - 1320 feet
