★ z.2 evaluate exponential functions lwe
use the following function rule to find $f(1)$.
$f(x) = -8(4)^x + 9$
$f(1) = \square$
submit

Explanation:

Step1: Substitute $x=1$ into function

$f(1) = -8(4)^{1} + 9$

Step2: Simplify the exponential term

$f(1) = -8(4) + 9$

Step3: Calculate multiplication first

$f(1) = -32 + 9$

Step4: Compute final sum

$f(1) = -23$

Answer:

-23
