A. 3 Evaluate functions 6 VY
Use the following function rule to find $f(6)$.
\[
\begin{array}{l}
f(x)=2 x^{2}-10 x \\
f(6)=\square I
\end{array}
\]

Solution
Solution Steps
Step 1: Substitute \( x = 6 \) into the function
Substitute \( x = 6 \) into the function \( f(x) = 2x^{2} - 10x \):
\[
f(6) = 2(6)^{2} - 10(6)
\]
Step 2: Calculate \( 6^{2} \)
Calculate \( 6^{2} \):
\[
6^{2} = 36
\]
Step 3: Multiply and simplify
Multiply and simplify the expression:
\[
f(6) = 2(36) - 10(6) = 72 - 60 = 12
\]
