To evaluate the function \( f(x) = 4^x + 5 \) at \( x = 2 \), we substitute \( 2 \) into the function:
\[
f(2) = 4^2 + 5
\]
Now, calculate \( 4^2 \):
\[
4^2 = 16
\]
Now, add \( 5 \):
\[
f(2) = 16 + 5 = 21
\]
Thus, the value of \( f(2) \) is \( 21 \).
\[
f(2) = 4^2 + 5
\]
Now, calculate \( 4^2 \):
\[
4^2 = 16
\]
Now, add \( 5 \):
\[
f(2) = 16 + 5 = 21
\]
Thus, the value of \( f(2) \) is \( 21 \).
