Respuesta :
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.
