Given the function f(x) = log5(x + 1), find the value of f−1(2).

OpenStudy (agent0smith):

\(\large f^{−1}(2)\) right?

OpenStudy (katecc379):

yes

OpenStudy (katecc379):

and its log base 5

OpenStudy (agent0smith):

It essentially means when y=2, find x. So solve for x \[\large 2 = \log_5 (x + 1)\]Start by raising both sides to the power of 5.

OpenStudy (katecc379):

it would be 24 correct?

OpenStudy (agent0smith):

\[\large 2 = \log_5 (24 + 1)\]

OpenStudy (katecc379):

what?

OpenStudy (agent0smith):

You said x=24, so is that a true statement, or no? \[\large 2 = \log_5 (24 + 1)\] \[\large 2 = \log_5 25\]
