ANSWER

EXPLANATION
The given function is a piecewise defined function.

is the y-value that corresponds to

To determine that y-value, we need to trace from

to where it meets the graph.
We then trace to the y-axis to determine the corresponding y-value as shown in the diagram.
From the graph, we can see that this x-value corresponds to a y-value of

This implies that, when

Therefore

See graph.

Step-by-step explanation:
-2*2-3x+5=f(x)
-2*2-3(-3)+5=f(x)
-4+9+5=f(x)
5+5=f(x)
10=f(x)
