Graph the quadratic functions y = 2x2 and y = 2x2 + 4 on a separate piece of paper. Using those graphs, compare and contrast the shape and position of the graphs. (3 points)

Y = 2x^2
h = Xv = B/2A = 0/4 = 0.
k = 2*0^2 = 0.
V(0,0).
Use the following points for graphing:

Y = 2x^2 + 4.
h = Xv = B/2A = 0/4 = 0.
k = Yv = 2*0^2 + 4 = 4.
