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.
