$y=\log_{3}x$ The change of base formula is: $\log_{b}M=\dfrac{\log_{a}M}{\log_{a}b}$ Express as a common logarithm by using the change of base formula shown to change the base of this logarithm to $10$: $\log_{3}x=\dfrac{\log x}{\log3}$ The function now is: $y=\dfrac{\log x}{\log3}$ The graph of this function is:
