What is the correct inverse function for f(x)=ln(3x)?
Maslowich

Let y = f(x)

y = ln(3x)

Exchange place with x and y.

x = ln(3y)

Solve for y.

y = (e^x)/3

Replace y with the inverse notation.

f^(-1) x = (e^x)/3

Done.

How do i express 11/20 as a percent??
Reptile [31]
So since a percent is out of 100 you would put 11/20 and right an equal sign next to that and the bottom fraction would be x/100. Then you would find the relationship between 100 and 20. 20 times 5 is 100 so then 11 times 5 is 55. 55% is your answer
