Question

The graph of the function y = x2 + 2 is shown. Which equation will shift the graph of the function to the right 2 units? A) y = x2 B) y = x2 + 4 C) y = x2 - 4 D) y = (x - 2)2 + 2

Answer 1

The solution is y = (x - 2)2 + 2. Squaring (x - 2) rather than just x will shift the graph to the right 2 units. This can be seen by trying some test points and plotting the function. So its D
