ALGEBRA :

We define the following functions:
(f)x=2x+5 (g)x=x^2-3 (h)x=7-x/3
◦ Compute (f – h)(4).
◦ Evaluate the following two compositions: (fog)(x) and (hog)(x) .
◦ Transform the g(x) function so that the graph is moved 6 units to the right and 7 units down.
◦ Find the inverse functions f^-1(x) and h^-1(x)
