Answer 1

Answer:

The output of the function when input is -3 is 3.

Step-by-step explanation:

The graph represents an equation of a line. To find the value at a point we need to check the vertical distance above the point on the $x$ axis.

When $x=-3$, we can observe that  the vertical distance of the line is 3. That is the ordered pair  $(-3,3)$ is a point on the lines.  So the output of the function when input is -3 is 3.
