To find the value of the function \( y = 3x^2 \) when \( x = 4 \), we can substitute 4 for \( x \):
\[
y = 3(4^2)
\]
Calculating \( 4^2 \):
\[
4^2 = 16
\]
Now substituting that back into the equation:
\[
y = 3(16) = 48
\]
Thus, the value of the function \( y \) when \( x = 4 \) is \( 48 \).
\[
y = 3(4^2)
\]
Calculating \( 4^2 \):
\[
4^2 = 16
\]
Now substituting that back into the equation:
\[
y = 3(16) = 48
\]
Thus, the value of the function \( y \) when \( x = 4 \) is \( 48 \).
