Suppose that g(x) = f(x) + 6. Which statement best compares the graph of g(x) with the graph of f(x)?

A) The graph of g(x) is the graph of f(x) shifted 6 units down.

B) The graph of g(x) is the graph of f(x) shifted 6 units to the left.

C) The graph of g(x) is the graph of f(x) shifted 6 units up.

Can someone please explain how to solve this problem to me? It would really help me out! Thanks!
