Step-by-Step Solution

Answer

The y-intercept of $y=\tan x$ is $0.$

Step 1. Given Information

The given function is $y= \tan x.$

We have to find the y-intercept.

Step 2. Finding the y- intercept

To find the y-intercept, substitute $0$ for x in a given function.

So,

 $$\begin{gathered} y=\tan 0 \\ y=0 [\tan 0=0] \end{gathered}$$
