hi, how can you tell whether the graph of a quadradic eqation of the form y=aXsquared + bX + c will have a min or max point

Do you know about the derivative of a function?
Hello, bieberashlee11!
Since this question in under "Beginning Algebra", I doubt that you've had Calculus.
If the \(\displaystyle a\) (coefficient of the \(\displaystyle x^2\)-term) is positive, the parabola opens upward: \(\displaystyle \cup\)
. . It has a minimum point.
If the \(\displaystyle a\) is negative, the parabola opens downward: \(\displaystyle \cap\)
. . It has a maximum point.
