Question

If f(x) = x3, which of the following describes the graph of f(x + 2)?
The graph of f(x + 2) is a vertical shift of f(x) = x3 two units down.
The graph of f(x + 2) is a horizontal shift of f(x) = x3 two units to the left.
The graph of f(x + 2) is a horizontal shift of f(x) = x3 two units to the right.
The graph of f(x + 2) is a vertical shift of f(x) = x3 two units up.

Answer 1

what is x3?
