    what is x3? If that is supposed to be x^3, please use the ^ symbol (SHIFT 6) when referring to an exponent.

    Graph them and see what the difference is.

    For the first one, is shifted 3 units to the left.

    If it were , it would be shifted 3 units to the right.

    Use the same sort of reasoning on the second problem.
