Question

what is $f(x) + f(x) + f(x)$? $3f(x)$
complete
$3f(x) = 3x^2$
complete
evaluate $3f(2) = \square$.
done

Explanation:

Step1: Determine the function f(x)

From \( 3f(x) = 3x^2 \), we can divide both sides by 3 to find \( f(x) \). So \( f(x)=\frac{3x^2}{3}=x^2 \).

Step2: Evaluate f(2)

Substitute \( x = 2 \) into \( f(x)=x^2 \). So \( f(2)=2^2 = 4 \).

Step3: Evaluate 3f(2)

Multiply the result of \( f(2) \) by 3. So \( 3f(2)=3\times4 = 12 \).

Answer:

12
