Question

z.2 evaluate exponential functions lwe
use the following function rule to find $f(4)$.
$f(x) = 12(4)^x + 3$
$f(4) = \square$
submit

Explanation:

Step1: Substitute $x=4$ into function

$f(4) = 12(4)^4 + 3$

Step2: Calculate $4^4$

$4^4 = 256$

Step3: Compute $12\times256$

$12\times256 = 3072$

Step4: Add 3 to the result

$3072 + 3 = 3075$

Answer:

3075
