Final answer:

To find f(-2) for the function f(x) = x², you substitute -2 in for x and square it, getting (-2)² which equals 4. Therefore, the answer is 4 (option a).

Step-by-step explanation:

The question asks us to find the value of f(-2) when f(x) = x². To do this, we substitute -2 for x in the function:

f(-2) = (-2)² = 4.

The correct answer from the given options is a) 4.
