    Need help with finding the turning point

    i have done all the work for these quadratic equations or common solutions, but now all i need to do is find the turning point using
    x=-b/2a

    13)y=x^2-4x+2


    14)y=-x^2+2x+2


    15)y=-x^2+6x-5


    16) y=2x-X^2

    Thanks for the help!!

    For each question:

    1. Identify the value of a, b and c and substitute into the given formula to get the x-coordinate.

    2. Substitute the x-coordinate from step 1 into the rule for your function to get the y-coordinate.

    If you need more help, please show all your work and say where you get stuck.
