Answer :
Answer:
The correct answer is option (3) 22.
Step-by-step explanation:
To find the value of f(-2)², we need to substitute -2 in place of x in the given equation f(x) = -3x² + 10.
f(-2)² = f(-2) * f(-2)
f(-2) = -3(-2)² + 10
= -3(4) + 10
= -12 + 10
= -2
Now, substitute f(-2) = -2 in the above equation:f(-2)² = (-2)² = 4
Therefore, the value of f(-2)² is 4.
Option (2) -2 is not the correct answer.
