Question

For the function in the graph, identify the values of f(1), f(3), and f (-1).

Answer 1

Explanation

We are given the following graph:

We are required to determine f(1), f(3), and f(-1) using the given graph.

This is achieved thus:

We determine the point of intersection of the x-coordinate to the given graph to arrive at the solution as follows:

Using the intersection made in the graph above, we have:

`\begin{gathered} f(1)=-1 \\ f(3)=1 \\ f(-1)=-3 \end{gathered}`

Hence, the answer is:

`-1,1,-3`

The third option is correct.
