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: (f?g)(x) and (h?g)(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).
