Answer:
3
Step-by-step explanation:
y = -9 when x = 3
When x = -4.5, the first definition of the function will be used since -4.5 is less than -3. In this region, y = -x implying that when x = -4.5, y= 4.5.
When x = 3, the last definition of the function will be used since 3 is greater than -2. In this region, y = -x^2 implying that when x = 3, y= -9.
