If the quadratic equation has the form y = ax 2and y = ax 2+ c, then their axis of symmetry must always be?

axis of symmetry , x = 0

Step-by-step explanation:

For the quadratic equation of the form ,

the axis of symmetry is the straight line  

( i)  Given equation y = ax² + 0x + 0

     b = 0, therefore axis of symmetry is x = 0

( ii ) Second equation y = ax² + 0x + c

    b = 0, therefore axis of symmetry is x = 0

answer: 20
