Consider the graph of $y=\tan x$y=tanx and state whether the following sentence is true or false.

Consider the graph of $y=\tan x$y=tanx and state whether the following sentence is true or false.

We want to identify how the coordinates of key points on the graph of $f\left(x\right)=\tan x$f(x)=tanx change as we apply a phase shift to produce the graph of $g\left(x\right)=\tan\left(x-60^\circ\right)$g(x)=tan(x60°).
