how do you graph x^2+4x1

x^2+4x1 = (x+2)^2 5
It is a parabola with its lowest point (vertex) at x=2,y = 5. The parabola opens upward. You graph it by assuming x values, computing y values that go with each x, plotting the data points on the grapt and "connecting the dots" wioth a smoothe curve.
Plotting a graph from x = 5 to +5 should be enough
