y=2x%5E2-3x%2B1 Start with the given equation.


Notice we have a quadratic equation in the form of y=ax%5E2%2Bbx%2Bc where a=2, b=-3, and c=1


Since a%3E0 (ie "a" is positive), this tells us that the parabola opens upward and the function has a minimum.

y=2x%5E2-3x%2B1
a=2
b=-3
c=1
:
since a is positive this opens upward and has a minimum
