3. quadratic formula

A. -b/2a

B. y = 2x

C.b^2 - 4ac

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

E. x = -b +/- (square root of) b^2 -4ac/2a


I think the answers are:

1. B
2. C
3. E

Are these correct?

Thanks!

  1. Not quite:

    A: x-coordinate of the vertex, also of the axis of symmetry
    B: not a quadratic at all; just a line
    C: the discriminant
    D: likely the parent equation
    E: quadratic formula. Note how the roots are equally spaced around x = -b/2a
