Which expression represents the composition g(f(x)) for the functions below?

f(x) = –3x2
g(x) = 3x

Ok seems you're in Algebra 1 :) well let me help you Franky :D

f(x) is inside g(x) so think of it as G(f(x)) = 3(-3x^2)      (SHOW EXPONENTS WITH ^ LIKE x^2 :D )

3(-3x^2) Now distribute :D

3*-3x = -9x
dont forget that exponent :P

g(f(x)) = -9x^2

Ithink ghe answer to this question is b just trying to others
