Question

If f(x) = −2x − 1 and g(x) = 6x − 1, find f[g(−2)]

−13

−25

25

Answer 1

first you have to find g(x) since it gave you what x is for g. In the equation that was given to you for g(x) where ever there is a x put a (-2) and figure it out and tell me what you get.

Answer 3

\[g(-2)=6(-2)-1\]
\[g(-2)=-12-1\]
\[g(-2)=-13\]
now you put -13 into x for f(x)
\[f(-13)=-2(-13)-1\]
\[f(-13)=26-1\]
\[f(-13)=25\]
