QUESTION :

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).
