Question

Can anybody help me get the answer to this problem? I don't need a huge explanation on how you got it but a very brief explanation as I am low on time. Thanks!

Answer 1

As given by the question

There are given that the graph.

Now,

The value of f(4) is:

`\begin{gathered} f(x)=y \\ f(4)=0 \end{gathered}`

And

If f(x)=5, then x is:

`\begin{gathered} f(x)=5 \\ f(x)=y \\ f(2)=5 \end{gathered}`

Hence, the value of f(4) is 0 and x is 2.
