    You said this was an "exponential function".....is THIS what you mean?

    y = 4x

    If so, substitute a domain element for "x", and evaluate.

    For example, if your function was y = 2x and your domain was [0, 3, 5], you might pick the domain element 3. Substitute that for x:

    y = 23
    Then do the arithmetic. 23 means 2*2*2, or 8.

    So, when x = 3, y = 8.

    If I have interpreted your function correctly, do the same sort of thing with it.
