Find $f[g(x)]$ And $g[f(x)]$
- $f(x)=5 x+9 ; g(x)=4 x-7$ A) $\mathrm{f}[\mathrm{g}(\mathrm{x})]=20 \mathrm{x}-26$

Multiple Choice

Find $f[g(x) ]$ and $g[f(x) ]$ .
- $f(x) =5 x+9 ; g(x) =4 x-7$

A) $\mathrm{f}[\mathrm{g}(\mathrm{x}) ]=20 \mathrm{x}-26$ $g[f(x) ]=20 x+29$
B) $f[g(x) ]=20 x+29$ $g[f(x) ]=20 x-26$
C) $\mathrm{f}[\mathrm{g}(\mathrm{x}) ]=20 \mathrm{x}-29$ $g[f(x) ]=20 x+26$
D) $\begin{aligned} f[g(x) ] & =20 x+26 \\ g[f(x) ] & =20 x-29\end{aligned}$
