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

y=1/3x

y=log3x

y = (1/3) x

y=log1/3x

B.) y=log3X Just took the test my guy!

XD

So if x is the exponent, 3 is the base, and y is the argument then this is an exponential function meaning the inverse is a logarithm so the answer can't be A or C. All you have to do is match the base, exponent, and argument into the setup for a logarithmic equation which is x=logby. Your answer should be x=log3y which looks similar to answer B.
