Question

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

Answer 1

9514 1404 393

Answer:

x = 0

Explanation:

When there is no linear term in the equation, the axis of symmetry is x=0.

__

The values 'a' and 'c' represent a vertical scale factor and a vertical translation, respectively. They do not change the axis of symmetry from that of the parent function, which is x=0.
