Question

How do you solve let f(x) = -4x + 7 and g(x) =10x- 6 find f(g(x))

Answer 1

\(\Large\color{red}{ \bf f(x) = -4x + 7 }\)

\(\Large\color{red}{ \bf g(x) =10x- 6 }\)

────────────────────────

\(\Large\color{red}{ \bf f(g(x)) = -4(10x-6) + 7 }\)
\(\Large\color{red}{ \bf f(g(x)) = -40x+24 + 7 }\)
\(\Large\color{red}{ \bf f(g(x)) = -40x+31 }\)
