Question

z.2 evaluate exponential functions lwe
use the following function rule to find $f(2)$.
$f(x) = 4^{x} + 9$
$f(2) = \square$

Explanation:

Step1: Substitute x=2 into function

$f(2) = 4^{2} + 9$

Step2: Calculate exponential term

$4^{2}=16$

Step3: Add the constant term

$16 + 9 = 25$

Answer:

25
