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 x-intercepts of the graph.
2) if it is open up, it has a minimum and if it is open down, it has a maximum .
1) If a is positive, graph is up. If a is negative, graph is down.
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 ? :)
Yes thank you so much!
as long as you understand .. no mention ;)
