$x$ $x$ - intercept: $- 2$ $-2$

Explanation:

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

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