Here is the question:
I have posted a link there to this thread so the OP can view my work.PRECAL INVERSE FUNCTION PROBLEM PLEASE HELP?
Clovis is standing at the edge of a cliff, which slopes 4 feet downward from him for every 1 horizontal foot. He launches a small model rocket from where he is standing.
With the origin of the coordinate system located where he is standing, and the x-axis extending horizontally, the path of the rocket is described by the formula y= -2x^2 + 120x.
a.) Give a function h = f(x) relating the height h of the rocket above the sloping ground to its x-coordinate.
0 = -2x^2 +124
b.) Find the maximum height of the rocket above the sloping ground. What is its x-coordinate when it is at its maximum height?
MAX: 31, 1922
c.) Clovis measures its height h of the rocket above the sloping ground while it is going up. Give a function x = g(h) relating the x-coordinate of the rocket to h.
The maximum I get for the rocket is (31, 1922)
I am pretty sure it is right because the answer in the back of the book is 31 - 1/2 sqrt3844 - 2h
so the 31 is probably correct!
I just need the answer to C (obviously), I'd really appreciate it if you could guide me through it rather than just answers.
Please no use of Calculus terms, I am in Precalc.
