#### Answer

Refer to the graph below.

#### Work Step by Step

To solve the given inequality by graphing, treat each side of the inequality as a function.
Graph:
$y_1=x^2$ (the red graph in the attached image below ) and
$y_2=x$. (the green graph in the attached image below)
The solution to the given inequality is the set of x values for which $y_1 \ge y_2$.
Notice that the graph shows that $y_1\ge y_2$ in the following intervals of $x$:
$(-\infty, 0]$ and $[(1, +\infty)$
Thus, the solution to the given inequality is:
$\color{blue}{\bf(-\infty, 0] \cup [1, +\infty)}$
Graph the inequality by plotting solid points at $x=0$ and $x=1$, then shading the region to the left of $0$ and to the right of $1$.
