Question

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

Answer 1

3log(3)

Answer 2

The answers are 1,8,10,27

Answer 3

You found f(2) @asdfghjkl24562

Answer 4

solve for x
\[2=\log_3(x+1)\]

Answer 5

ohhhhhhh

Answer 6

hint:
using the definition of logarithm, we can write:
\[\Large x + 1 = {3^y}\]

Answer 7

Oh the logarithmic is the in the inverse of exponential functions, so all you have to do is cinvert it to an exponential function and substitute the velue

Answer 8

You guys are amazing

Answer 9

\[(2)+1=3^{y}\]

Answer 10

thanks!

Answer 11

3=3\[^{y}\]

Answer 12

\[3 = 3^{y}\]

Answer 13

it's suppose to be
\[3^2=x+1\]

Answer 14

no

Answer 15

\[f^{-1}(2) =x \text{ implies } f(x)=2 \\ \text{ so we need to solve } 2=\log_3(x+1) \\ \text{ and converting to exponential form gives } \\ 3^2=x+1\]

Answer 16

Oh ya
