Varvara68 [4.7K]

Answer:

$a^{14+n}$

Step-by-step explanation:

You add the exponents when the number/variable is the same, so:

If f(x) = log3 (x + 1), what is f−1(2)

ki77a [65]

Firstly, we'll find y = f⁻¹(x):

$f(x)=\log_3(x+1)\\\\
x=\log_3(y+1)\\\\
y+1=3^x\\\\
y=3^x-1\\\\
f^{-1}(x)=3^x-1
$

So:

$f^{-1}(x)=3^x-1\\\\
f^{-1}(2)=3^2-1\\\\
f^{-1}(2)=9-1\\\\
\boxed{f^{-1}(2)=8}$
