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

the 3rd one because if you look at it properly, the only translation is 2 up, that means (since there's no x shift in the graph) the axis of symmetry is x=0

Answer 2

ok thanks
