To find f ( − 9) we can substitute −9 for each occurrence of x in f (x) f (x) = 2x −1 becomes: F(x) = 3x2 + 2x+ 1 (2) what do we end up doing with this function? Write a formula for each of the following functions and then simplify.

(gof) (2x) = g (f (2x)) = g (4x + 1) now substitute this expression (4x + 1) in to function g in place of the x value. F (x +1) = 2(x + 1) − 1. F (−9) = (2 × −9. F (g(x)) f ( g ( x)) evaluate f (g(x)) f ( g ( x)) by substituting in the value of g g into f f.
