Question

H(x)=√(x+7). Find f and g so that h=f o g

Answer 1

(D) f(x)=√x, g(x)=x+7

Step-by-step explanation:

Given the functions:

`\begin{gathered} f(x)=\sqrt[]{x} \\ g(x)=x+7 \end{gathered}`

The composite function h(x)=(f o g)(x) is:

`\begin{gathered} h(x)=(f\circ g)(x) \\ =f(g(x)) \\ =\sqrt[]{g(x)} \\ =\sqrt[]{x+7} \end{gathered}`

The correct choice is D.
