You have to substitute the x value with 3, so your new equation is f(3) = -2(3)^2 - 4. Your answer is -22. :) 

Answer:

f(2) = -22.

Step-by-step explanation:

Given : ƒ(x) = –2x² – 4 for x = 3.

To find : Evaluate.

Solution :We have given

ƒ(x) = –2x² – 4 .

For x = 3.

f(2) =  –2 (3)² – 4 .

f(2) = -2 ( 9) - 4 .

f(2) = -18 - 4 .

f(2) = -22.

Therefore, f(2) = -22.
