Use transformations to help describe the differences and the similarities in the graphs of the quadratic functions. Verify using a graphing calculator.y = 2x2 - 1, y = 2x2 + 4
A. The graph y = 2x2 + 4 is shifted vertically 5 units below y = 2x2 - 1.
B. The graph y = 2x2 + 4 is shifted vertically 5 units above y = 2x2 - 1.
C. The graph y = 2x2 + 4 is shifted horizontally 5 units to the left of y = 2x2 - 1.
D. The graph y = 2x2 + 4 is shifted horizontally 5 units to the right of y = 2x2 - 1.
