Question

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

Answer 1

A? im pretty sure

Answer 2

eek this is a weird question hold on a second.

Answer 3

that is wrong, its going to be B. Same vertex just opposite directions. Final answer: B.

Answer 4

Thanks!
