Question

Which equation has a graph that is a parabola with a vertex at (–1, –1)?
y = (x – 1)2 + 1
y = (x – 1)2 – 1
y = (x + 1)2 + 1
y = (x + 1)2 – 1

Which equation is y = 6x2 + 12x – 10 rewritten in vertex form?
y = 6(x + 1)2 – 11
y = 6(x + 1)2 – 10
y = 6(x + 1)2 – 4
y = 6(x + 1)2 – 16

Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form?

Which pair of equations generates graphs with the same vertex?
y = –(x + 4)2 and y = (x – 4)2
y = –4x2 and y = 4x2
y = –x2 – 4 and y = x2 + 4
y = (x – 4)2 and y = x2 + 4

Which equation is y = 2x2 – 8x + 9 rewritten in vertex form

Hey, welcome to Openstudy lol.
Anyways, the math section is the most active, and lol this question is related to math. So post it there :)
