Y = x^2 + 2x - 1 = x^2 + 2x + 1 - 1 - 1 = (x + 1)^2 - 2
The vertex of a parabola given by y = a(x - h)^2 + k is (h, k).
Therefore, the vertex of y = (x + 1)^2 - 2 is (-1, -2)
idk what kind of math problem but, if its just simple id us PEMDAS
All of them except B and C. Probabilities must add to 1 and none of the p's can be negative
