Question

use the following function rule to find f(1).
$f(x) = -9(8)^x - 10$
$f(1) = \square$
submit

Explanation:

Step1: Substitute x=1 into function

$f(1) = -9(8)^1 - 10$

Step2: Simplify exponential term

$f(1) = -9(8) - 10$

Step3: Calculate multiplication first

$f(1) = -72 - 10$

Step4: Compute final subtraction

$f(1) = -82$

Answer:

$-82$
