I need help creating a quadratic equation in the form y = ax2 + bx + c. Use complete sentences and show all work to determine the following:
1) Does the graph open up or down? How do you know?
2) Explain whether the graph has a maximum or minimum point.
3) Find the vertex and xintercepts of the graph.

To find the x axis intercept, use the quadratic formula OR ANY OTHER to find the roots, If 1 root then it means minimum OR maximum is on the axis, If 2 roots then it shows 2 points on the axis , If no roots are possible then , axis is not intercepted . Understood @emmaclausen ? :)
