11. Solve.

12. Solve by using the quadratic formula.

13. Objective - To solve quadratic equations using the quadratic formula.

14. Solve by using the quadratic formula.

15. Often we graph a quadratic function. Graph
When we graph a quadratic equation, we must first find the coordinates of the vertex. To find the x-coordinate of the vertex, we must use the formula

16. Let’s graph this parabola
The x-coordinate of the vertex is equal to
a = 1 and b = -4
Vertex -2 -1 1 2 3 4 5 6

17. On your graph
Make sure you put arrows on the end of your graph
Write the equation next to the parabola
Label the vertex and write its coordinates
Circle and identify the roots
Draw the axis of symmetry and write its equation
Does the graph have a maximum or minimum? What is it?
Identify the domain and range
What type of orientation does the graph have.
