State the conditions of the values a, b, and c so that the quadratic formula f(x)=ax^2+bx+c has no x-intercepts.
I don't know how to set this up.

Tinkermom said:Ok, I don't understand how you got the y-coordinate of the vertex. I understand you put the x-coordinate into ax^2+bx+c, but I don't see how you came to the c-b^2/4a.
