I don't see any answer choices, so I'm just going to attach an image of the equations graphed on Desmos.
Desmos is a free, online graphing calculator that works really well for problems like this. If you want to get a better view of the graphs and to be able to "interact" with them, just go to the desmos website and put in your equation(s). The picture that I've attached might not be very helpful because it doesn't show the full extent of the graph, so you might want to check it out and do it yourself.
Hope this helps!
