Question

how do i graph a parabola with vertex (-9,-8)?

Answer 1

i need to put it in y graphing calc

Answer 2

vertex form is a(x-h)^2 + k
where the vertex is (h,k)
so plug in -9,-8
->y = a(x+9)^2 - 8
where a determines how wide or skinny the parabola is
you need another point to determine a

Answer 3

you could just pick an a to put in a graphing calculator

Answer 4

i have 3 points the first being the vertex points are (-8,-9) (-7,-8) (-7,-10)
