    1. Y = x^2+3x-10.

    Y = a(x-h)^2 + k.

    h = Xv = -b/2a = -3/2.
    k = (-3/2)^2 + 3(-3/2) - 10 = -49/4.
    V(h,k).
    V(-3/2,-49/4).

    Y = 1(X+3/2)^2 - 49/4.

    2. Y = x^2 - 9x.

    Y = a(X-h)^2 + k.

    h = Xv = -b/2a = 9/2.
    k = (9/2)^2- 9(9/2) = -81/4.
    V(h,k) = (9/2,-81/4).

    Y = 1(X-9/2)^2 - 81/4.

    8. Y = (x-3)^2 + 1.
    Y = x^2 _ 6x + 9 + 1.

    Y = X^2 - 6x + 10.

    The remaining problems are similar to
    those I've solved.
