Question

=
Which of the following is the inverse of y=3"?

Answer 1

[B]
`y=log_3x`

Explanation:

Given:

`y=3^x`

Exchange the variables:

`x=3^y`

Putting the variable y on the left side of the equation:

`3^y=x`

Applying the logarithm properties:

`y=log_3(x)`

Thus,

`f^-^1=log_3(x)`

Hence, the answer is [B]
`y=log_3x`
