g(x) = 5x - 1

______________________

Find each of the following functions and their domains.
f(x) = 1 - 3x
g(x) = cos(x)


_____________
(a) If g(x) = 2x + 2 and h(x) = 4x2 + 8x + 9, find a function f such that f compose g = h. (Think about what operations you would have to perform on the formula for g to end up with the formula for h.)
f =


(b) If f(x) = 5x + 7 and h(x) = 5x2 + 5x + 2, find a function g such that f compose g = h.
g(x) =
