Given: f (x) = 4^x + 5, evaluate the function for: f (2)

Answer 1

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 \( 21 \).
