Bonus Knowledge
To find the inverse function
of
, we start by letting
:
Next, we solve for
in terms of
. We begin by cross-multiplying:
Expanding this gives:
Next, we move all terms involving
to one side:
Factoring out
from the left side:
Now, we solve for
:
This represents the inverse function. To express it more clearly, we switch
back to
:
Thus, the inverse function is:
