plug in 2 for X in the f(x) equation. Then plug that value you got for f(x) into the X value for g(x)

Okay I get -6 and 9...

OpenStudy (anonymous):

\[(gof)(2)=g(f(2))=-2(-2 \times 2^{2}+3 \times 2-4)-3=2 \times 2^{2}-6 \times 2+8-3\] \[=2 \times 4-12+5=8-8=0\]

OpenStudy (anonymous):

th epossible answers are -15, 9, -39, and 15.

OpenStudy (anonymous):

\[-2(2^2)+6-4\] = -6

OpenStudy (anonymous):

-2(-6)-3 12-3 =9

OpenStudy (anonymous):

The answer of gof(2)) is = 9

OpenStudy (anonymous):

OpenStudy (anonymous):

Its basically putting the function of F into the x value or whatever variable G has.
