r(x)= x^2+x-6

--------

x^2-x-2

C = -6 = -1(6) = -2(3).

Select the pair of factors whose sum = 1(B):

Y = (x-2)(x+3) = 0

Solution set: X = -2, and 3 = x-Intercepts.

Axis: x = Xv = -B/2A = -1/2. = h.

k = Yv = (1/2)^2 -1/2 - 6

k = -6.25.

V(h,k) = V(-0.5,-6.25)

The following points can be used for graphing:

(x,y).

(-3,0)

(-2,-4)

(-1,-6)

V(-0.5,-6.25)

(1,-4)

(2,0)

(3,6)
