This is also driving my crazy. I'm asked to write in standard form of the quadratic function. It gives me a picture of a parabola and 3 points, 1 of them is the vertex.

Here's an example:
I don't get it at all.
Recall that the standard form is , where is the vertex.
Then plug in any point that is given to you in the graph above to find .
oops lol thanks. Otherwise I have imaginary numbers. Forgot to put the negative infront of x^2 so the graph opens downward. But skeeter how would I know that is the graph and not just using the formula

you can't know w/o additional info ... both have the same sum/product of roots.
