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
1)(fog)(x)
2) (hog) (x)
Graph the g(x) function and transform it  so that the graph is moved 6 units to the right and 7 units down.
Find the inverse functions
3) f^(-1)(x)
4) h^(-1)(x)
