a) (2) b) (3a)

Reiny,
"Find each of the indicated function value"
implies you want 4²x  5x + 9 = 2
or do you want to find f(2) ?
I have a feeling it is the second interpretation.
if f(x) = 4²x  5x + 9
f(2) = 4(2)^2  5(2) + 9
= 15
f(3a) = 4(3a)^2  5(3a) + 9
= 36a^2 + 15a + 9
Your next posting has the same kind of questions.
