Which of the following is the inverse of y=3x?
y=1/3x
y=log3x
y=(1/3)x
y=log1/3x

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.

Idon’t exactly understand but i think dbc=rst
