    How do i solve this? :confused: The question says: Given that the point P=(-2,4) is on the graph of y=f(x) and g(x)=2f(x-1)-3; find the point on the graph of g(x) corresponding to the point P.

    Thanks in advance,
    Sky

    Hint: Another way of saying that the point P (-2,4) is on the graph of y = f(x) is to say:

    f(-2) = 4

    g(x) scales and shifts the graph of f(x)

    What, exactly, is meant by "the point on the graph of g(x) corresponding to the point P"?
