learn with an exan
use the following function rule to find $f(2)$.
$f(x) = 3(9)^x + 6$
$f(2) = $
submit

Explanation:

Step1: Substitute x=2 into function

$f(2) = 3(9)^2 + 6$

Step2: Calculate exponent term

$9^2 = 81$, so $f(2) = 3\times81 + 6$

Step3: Compute multiplication

$3\times81 = 243$, so $f(2) = 243 + 6$

Step4: Perform final addition

$243 + 6 = 249$

Answer:

249
