# How do you graph y=3tanx?

Feb 18, 2018

$y$ is the standard graph of $f \left(x\right) = \tan x$ scaled by 3 units.

#### Explanation:

$y = 3 \tan x$

Consider the standard graph of $f \left(x\right) = \tan x$ below.

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

Then, $y = 3 \times f \left(x\right)$ as represented by the graph below.
