Question

Graph has a vertex at (−1,−2) and passes the point (0,−1). Find the quadratic function.

Answer 1

\[y=a(x-h)^2+k\]

Answer 2

Plug in and solve for a. h = -1, k = -2, x = 0, y = -1

Answer 3

hmm i got -3(x+1)^2 + 3

Answer 4

a(x+1)^2 + 4
a(0+1)^2+4
a(1)+4
-1=1a+4
-5==1a
a=-5

Answer 5

-5(x+1)^2 + 4??

Answer 6

-1=a(0+1)^2-1
-1=a(1)-1
a=
