  1. (x+5)^2 = 4 (y + 1/2)

    vertex at (-5, -1/2)

    so for the left half x is always less than (to the left of) -5
    an y is above -1/2
    I do not know what else to say

    Great! I understand now that C0=f(a) c1=f'(a) c2=f"(a)/2 Now, If I am to find the parabolization of the equation x^2-x at x=2, then c0=x^2-x=2^2-2=2 c1=2x-1=2(2)-1=3 c2=2/2=1 So, the equation (taken from c0+c1(x-a)+c2(x-a)^2) is
