Question

z.2 evaluate exponential functions lwe
use the following function rule to find $f(0)$.
$f(x) = 8^{x} - 10$
$f(0) = \square$

Explanation:

Step1: Substitute $x=0$ into function

$f(0) = 8^{0} - 10$

Step2: Evaluate exponential term

$8^0 = 1$, so $f(0) = 1 - 10$

Step3: Calculate final value

$f(0) = -9$

Answer:

$-9$
