Question

I. Let f(x) = 2x – 1, g(x) = 3x, and h(x) = x2
+ 1. Compute the following:
6. h o g(x)

Answer 1

h o g(x) would equal h(g(x)). By substituting, ou first get h(3x). By substituting 3x into the h formula, you would get (3x)^2 + 1, which would equal 9x^2 + 1

Answer 2

h(g(x)) =
h(3x) =
(3x)^2 + 1 =
9x^2 + 1
