Describe what you know about a quadratic function. Use terms like standard form, vertex, positive, negative, parabola, up, down, and axis of symmetry. by Marie Wadih https://padlet.com/mwadih1/n7hzgrdboz51 en-us 2015-03-23 17:35:28 UTC 2026-02-09 20:40:10 UTC hello@padlet.com http://t3.gstatic.com/images?q=tbn:ANd9GcQsIAcLEQJzjyAAOh-jL-L47c92xbQlaIs82WYSLgKX8TuEj3pgFA Wadih mwadih1 https://padlet.com/mwadih1/n7hzgrdboz51/wish/54519667 The standard form of a quadratic equation is

then you can use the result of that formula to

find the vertex.

When it is the lowest point it is called a minimum.

Parabolas face down when A=Negative

The highest point is called a MAXIMUM!!!!

O YEAH!!!!
