السلام عليكم ورحمه الله

معليش ممكن احد يساعدني في حل دي الاسئله =(

f(x) = x2 - 2
g(x) = 5x - 3

f g =
g f =
g g =
f f =


+++++++++++++++

(a) If g(x) = 2x + 2 and h(x) = 4x2 + 8x + 6, find a function f such that f 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 =
1


(b) If f(x) = 5x + 8 and h(x) = 5x2 + 5x + 3, find a function g such that f g = h.
g(x) =
