Answer 1

Answer:

4

Step-by-step explanation:

This is a piece wise function. A piece wise function has 2 or more functions which only work on specific intervals. To find when x = -2, first find the interval that contains x = -2.

The interval is x < 0. This interval corresponds to the function x².

So f(-2) will be (-2)² = 4
