Answer:

f(-3) = 1

Step-by-step explanation:

The given function is f(a) = -2a^2 -5a + 4

We need to find f(-3)

This is called evaluating function.

To find f(-3) replace a by -3 in the given function

f(3) = -2(-3)^2 - 5(-3) + 4

= -2(9) +15 + 4

= -18 + 15 + 4

= -3 + 4

f(-3) = 1

Therefore, the answer is 1.
