Answer:
A. H(x) is an inverse of F(x)
Step-by-step explanation:
The given functions are:



We compose F(x) and G(x) to get:






Hence G(x) is not an inverse of F(x).
We now compose H(x) and G(x).



We simplify to get:


Since
, H(x) is an inverse of F(x)
Pi/3 is in the first quadrant, and all trigonometric functions are positive in the first quadrant,
Therefore, cos pi/3 is positive.

Hello there!
Solve for x:
-3x(x-8)-7x=12
-3x^2+24x-7x=12
-3x^2+17x+12=0
