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
1. Parent Quadratic Equation
2. Coordinate of the vertex
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!
