Answer:
f(-3) = 1
Step-by-step explanation:
The given function is [tex]f(a) = -2a^2 -5a + 4[/tex]
We need to find f(-3)
This is called evaluating function.
To find f(-3) replace a by -3 in the given function
[tex]f(3) = -2(-3)^2 - 5(-3) + 4[/tex]
= -2(9) +15 + 4
= -18 + 15 + 4
= -3 + 4
f(-3) = 1
Therefore, the answer is 1.
