Help I do not understand this at all. I read over the chapter numerous times and still confused.
We define the following functions:
f(x)=2x+5
g(x)=x^2-3
h(x)=7-x/3
o Compute (f – h)(4).
o Evaluate the following two compositions: (fog)(x)and (hog)(x) .
o Transform the g(x) function so that the graph is moved 6 units to the right and 7 units down.
o Find the inverse functions f^-1(x) and h^-1(x) .

The goal is to learn to use function notation and apply definitions of functions and function notation.
Looking at the first task, (f-h)(4), seems to be just take the two functions, f and h, form their difference, and then evaluate this resulting function at x=4.
=
At x=4, the function becomes
