Question

Given the two functions $f$ and $g$ , find $fg$ and identify the domain.

$f\left(x\right)=\sqrt{x}$ , $g\left(x\right)=x+17$

Accepted Answer

$\left(fg\right)\left(x\right)=\sqrt{x}\left(x+17\right)$ , Domain: $\left\lbrack0,\infty\right)$

Answer

$\left(fg\right)\left(x\right)=\sqrt{x}\left(x+17\right)$ , Domain: $\left(-\infty,0\right\rbrack$

Answer

$\left(fg\right)\left(x\right)=\sqrt{x}\left(x+17\right)$ , Domain: $\left(0,\infty\right)$

Answer

$\left(fg\right)\left(x\right)=\sqrt{x}\left(x+17\right)$ , Domain: $\left\lbrack0,\infty\right)$
