On an Apple computer this is usually apple shift + (and zooming out is apple -).
This graph has three functions. Function f(x) is a straight line colored in blue. There are two constant functions, colored in red, at h(x)=-2 and g(x)=4. The graph of f(x) crosses those two horizontal lines at (-3,-2) and (3,4).
Use interval notation in your answers. Use inf to represent infinity.
