Question

Find F^-1(x) f(x)=ln(x+3)

Answer 1

is this because ln = e that we have e^(x+3)

Answer 2

or is it because the inverse of ln is e

Answer 3

im kinda confused on that one

Answer 4

\[f(x)=y=\ln (x+3)\]
Interchanging x and y to find the inverse:
\[x=\ln (y+3)\]
Therefore
\[e ^{x}=y+3\]
\[f ^{-1}(x)=e ^{x}-3\]

Answer 5

Ok I understand now ty

Answer 6

You're welcome :)
