# How do you graph  log_2(x-4)?

Aug 19, 2017

Well, it should be some form of the logarithmic function:

$f \left(x\right) = \ln \left(x\right)$:

graph{lnx [-10, 10, -5, 5]}

The function appears to shift $4$ units to the right, so we have

$f \left(x\right) = {\log}_{2} \left(x - 4\right)$:

graph{ln (x-4) [-10, 10, -5, 5]}
