Two questions?
18.Find (fog) if f(x) = 2x  1 and g(x) = x + 2.
A. 2x  3
B. 2x + 1
C. 2x  1
D. 2x + 3
I think it's B (2x + 1)
what I did to get my answer?
I combined like terms (2x and x) = 2x or 3x?
and then I added 1 + 2 and got 1.
19.
What is the change that occurs to the parent function f(x) = x2 given the function f(x) = (x + 1)2  5.
A. The graph moves 1 unit to the left and 5 units up.
B. The graph moves 1 unit to the left and 5 units down.
C. The graph moves 1 unit to the right and 5 units down.
D. The graph moves 1 unit to the right and 5 u
