y = x^2 − 2x − 3?

Answer 1

@aloud

Answer 2

plug it in the desmoes

Answer 3

IDK wat a directrix is

Answer 4

If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an equation of (y - k)^2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p.

Answer 5

So would it be y=4

Answer 6

@aloud would the answer be y=4

Answer 7

y=-4 x=1

Answer 8

so that a yes lol

Answer 9

yes
