Am I correct in these problems?
1. f(x)= 2x + 3
g(x) = 2x^2 + 2x
Find f(g(x))
2(2x^2+2x)+3
=4x(x+1)+3
2. f(x) = 5x + 3
g(x) = 2x^2 -2x + 2
Find (fg(x))
(5x+3)(2x^2-2x+2)
2(5x+3)(x2-x+1)
looks good to me.
Though I'd be consistent and either completely factor the result, or expand it. #1 is some of each.
