Question

which function is the inverse function of f(x)=7^x?

Answer 1

y=7^x
do you know how to write this in the equivalent logarithm form

Answer 2

NOPE BRO

Answer 3

\[y=a^x \implies \log_a(y)=x\]

Answer 4

anyways this solves the equation for x
and then you can just replace y with x and x with f^(-1)(x) after that step
