## University Calculus: Early Transcendentals (3rd Edition)

$\mathrm{See\:the\:graph\:below.}$ The first piece of the given function is represented by red in the graph below, while the second piece with blue.
The first part of the graph is composed of a hyperbola while the second represents a straight line. Graph the function $\ y=\frac{1}{x}\$ and apply the constraint $\ (-\infty,0).$ After that, graph the second piece of the function $\ y=x\$ and apply the constraint $\ [0,\infty).$ You may notice that the point $\ x=0\$ is included in the domain and is represented by the blue filled circle.
