Question

I know how to find answers I get them mixed up every time

Answer 1

We are to evaluate for

`\begin{gathered} f(2)=? \\ f(x)=-1,x=? \end{gathered}`

Let us upload the image and evaluate for f(2)

From the image, we can observe that

`f(2)=1`

Let us upload the second image and evaluate for x, when f(x)=-1

From the image above, the value of x for which f(x)=-1 is

`x=0`

Final answers

`\begin{gathered} a)\text{ 1} \\ b)\text{ 0} \end{gathered}`
