    The points P (4, -2) lies on the curve y=f(x). Find the coordinates of the image of P when the curve is transformed to y=f(5x).

    I know that this shrinks the curve horizontally (i.e. y stays the same, x changes), but I don't know how to find the new value for x. Would it just be 4/5?

    Thanks!
