Question

Question 4 of 10 f(x) = x. What is g(x)? f(x)= x g(x) (2, 1) x

Answer 1

`f(x)=x^2`

Given the point:

`\begin{gathered} (2,1) \\ x=2,g(2)=1 \\ so\colon \\ g(2)=ax^2=1 \\ a(2^2)=1 \\ solve_{\text{ }}for_{\text{ }}a\colon \\ a=(1)/(2^2)=(1)/(4) \end{gathered}`

Therefore:

`g(x)=((1)/(2)x)^2`
