How to use a graphing calculator to find the limit of $x|x-4|$ as x approaches -1?

Hunter Hendricks

Use your calculator (or other graphing software/app) to plot the graph, then look to see what happens at $x=-1$
Hence, If $f\left(x\right)=x|x-4|$, then as f(x) is continuous, the limit is $f\left(-1\right)=-5$
