    Q in derivatives

    Q Find all older derivatives

    y = X^4/2 = 3/2X^2 -X

    y4 = 2X^2 - 3 x ^ 1 - 0
    y4 = 4X^1 - 3 -0
    y4 = 7

    None of this makes any sense. What is the line I have highlighted in red meant to mean? What do all the y4's mean? The 4th derivative of y?

    Please re-post the question in such a way that it can be understood.
