  3. Wednesday, October 15, 2014 Review of Quadratic FunctionsEQ: How do we graph a quadratic function? M2 Unit 1B: Day 4 Lesson 3.2

  4. Quadratic Functions What is the standard form of a quadratic function. Standard Form What is the vertex form of a quadratic function. Vertex Form Course 3

  5. How do we find the axis of symmetry and vertex if we know the vertex form? Vertex Form We use to find the axis of symmetry. Then we substitute this value into the equation and to find the y-coordinate for the vertex.

  6. Standard Form How do we find the y-intercept? We identity “c”. It is always the y-intercept if the equation is in standard form!

  7. Vertex Form How do we find the y-intercept? We substitute “zero” for the x-coordinate solve for f(x) or y.

  8. Graph. Axis of symmetry: h = -1 k = -1 Vertex: Y-intercept: One more point: Max or Min? maximum Domain: Range: All real numbers

  9. Graph. Axis of symmetry: Vertex: Y-intercept: One more point: Max or Min? maximum Domain: Range: All real numbers

  10. Graph. Axis of symmetry: Vertex: Y-intercept: One more point: You can use the original factor to get two more points! Max or Min? maximum All real numbers Domain: Range:

  11. Converting forms

  12. Find the minimum or maximum value of the function. This parabola will have a minimum ! The minimum value of the function is the y-coordinate of the vertex! Vertex (-3,-18) so the minimum value of the function is -18.
