Given [tex]f(x) = -3x^2 + 10[/tex], what is the value of [tex]f(-2)[/tex]?

A. -26
B. -2
C. 22
D. 46

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.
