Question

If f(x) = x2, which of the following describes the graph of f(x) + 4?
The graph of f(x) + 4 is a vertical shift of f(x) = x2 four units up.
The graph of f(x) + 4 is a vertical shift of f(x) = x2 four units down.
The graph of f(x) + 4 is a horizontal shift of f(x) = x2 four units to the right.
The graph of f(x) + 4 is a horizontal shift of f(x) = x2 four units to the left.
