Question

How to do make the equation f(x) = e^x be in terms of y?

Answer 1

\[f(x)=e^x \to f(y) = ??\]

Answer 2

By y you probably mean f(x) = y = e^x. Then taking the natural logarithm of both sides, x = ln(y).

Answer 3

\[y=e^x\]
take logarithm to base e on both sides
\[\log y= x\]

Answer 4

The domain (or range) of y would have to be restricted however to (0,infinity).

Answer 5

This is important.
