Answer:
The value of f(-a) would be 3a^2 + 3.
Explanation:
To find the value of f(-a), we need to substitute -a into the function f(x) = 3x^2 + 3.
Substituting -a for x, we have:
f(-a) = 3(-a)^2 + 3
Now, let's simplify this expression:
f(-a) = 3(a^2) + 3
f(-a) = 3a^2 + 3
Therefore, the value of f(-a) is 3a^2 + 3.
