Question

Which must be true of a quadratic function whose vertex is the same as its y-intercept?

Answer 1

If it is the same as the Y- intercept, then that makes the quadratic function equal. The line passes through the origin ( 0,0 ).

Answer 2

Explanation:

The graph passes through the origin. It could either open up or open down. The quadratic has two zeros, both at (0, 0).
