 
Hi Max, I would start by plotting some points. Let me show you with y = x^{2} + 1. I chose values x = 0, 1, 1, 2 and 2 and for each I found the value of y using y = x^{2} + 1.
Then I plotted these points on an xy coordinate system Then I sketched a graph through these points Now try your example,
