i hate these i always get them wrong

anonymous · Answer

Well an axis of symmetry is an AXIS. Therefore, its just a straight line going up or down. Which means you only need the x-variable:

ex) The axis of symmetry for the parabola y = x^2 is x=0

anonymous · Answer

so then it would be sometimes right

anonymous · Answer

so the equation for an axis of symmetry NEVER has the both the x and y.

oh ok thank you
