For x-intercepts "b" and "c", a quadratic can be written as
  y = a(x -b)(x -c)

You know the x-intercepts, so you can write the equation as
  y = a(x +2)(x -3) . . . . . . eliminates the first two answer choices

Substituting (x, y) = (-1, 2), you have
  2 = a(-1+2)(-1-3) = -4a
Then dividing by -4 gives
  -2/4 = a = -1/2 . . . . . corresponds to the third answer choice

The appropriate selection is
  y = -1/2 (x + 2)(x - 3)
