  1. GRAPHING A QUADRATIC FUNCTION IN STANDARD FORM THAT CANNOT BE FACTORED

  2. LEARNING GOALS • Find x-intercepts of a quadratic relation using the quadratic formula • Use the x-intercepts to find the vertex • then use them to sketch the graph

  3. GRAPHING A QUADRATIC RELATION THAT CANNOT BE FACTORED STEPS 1) Write the equation in standard form if it is not already in it. 2) Find the x-intercepts using the quadratic formula. 3) Find the vertex x using 4) Find the vertex y by substituting in the vertex x into the original equation.

  4. Example: SOLUTION:

  5. ...Example continued Vertex x = Vertex y =

  6. GRAPH:

  7. Summary of 3 forms of Quadratic Functions 1) Vertex Form 2) Factored Form 3) Standard Form

  8. Example 2: Fill in the chart.

  9. Example 2: Fill in the chart.

  10. Example 2: Fill in the chart (find x-intercepts using factoring or Q .F.)
