Write a simplified expression representing each of the requested compositions of the following two functions:
f(x) =x+2/-4
g(x) = -4x - 2
What is f(g(x))?
What is g(f(x))?
Are the two functions inverses of one another?

Step-by-step explanation:

The graph is a nonlinear graph.

The hang time is 3 seconds.

The h- coordinate of the top of the bump is about 11 m, so the maximum height is 11 m after rounding to the nearest meter.

For t between 0 and 1.5, the height is increasing.

I hope this helps.  I found  it on Khan Academy.
