Question

Choose the equation below whose axis of symmetry is x = 0.

y = x2 + 2x

y = x2 − 16x + 58

y = x2 + 2

y = x2 − 4x + 2

Answer 1

x = -b/2a = 0 <=> b = 0
Can you choose now?

Answer 2

idk

Answer 3

what's b?

Answer 4

y = x2 − 16x + 58

Answer 5

y = x² + 2x
In this equation b = 2

Answer 6

Choose the option with b = 0

Answer 7

is the answer b ?

Answer 8

y = x²− 16x + 58
Nope, b = -16

Answer 9

c?

Answer 10

y = x² + 2
Yes, no b = 0 here

Answer 11

Yes, no b => b = 0

Answer 12

Its c ? youre confusing me ;o llol
