The axis of symmentry

Question

What is the axis of symmentry for

y2 - 6y + 9 -x = 0

Answer 1

Hi Chyna

 

This is a parabola that opens to the right, whose vertex is at (0,3)

 

So the axis of symmetry is is the horizontal line going through y = 3.

 

The axis of symmetry, therefore is

 

y=3
