Question

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

Answer 1

axis of symmetry , x = 0

Explanation:

For the quadratic equation of the form
`ax^2 + bx + c`,

the axis of symmetry is the straight line
`x =- (b)/(2a)`

( 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
