# How do I solve f(x)=(x+2)/(x^2+1) on a TI-84?

$x$- intercept: $- 2$

#### Explanation:

You are setting the equation to make it equal to $0$ and solving for where $x = 0$. Basically, you are finding the interception point of $f \left(x\right)$ and the $x$-axis.

Graph $f \left(x\right)$ on the TI-84, then plot the $y = 0$ line.
