السلام عليكم ورحمه الله
معليش ممكن احد يساعدني في حل دي الاسئله =(
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 +

h(
x) =

3, find a function
g such that
f g =
h.
