  1. Graph of Quadratic Functions

  2. Classify Put in STANDARD FORM x4+ 3x – 2x2 +7x3+6

  3. Find the missing side length Perimeter = 11x + 7 5x + 8 2x - 4

  4. Quadratic function A QUADRATIC FUNCTION is a function that can be written in the standard form: f(x) = ax2 + bx + c where a≠ 0

  5. Graphing quadratic The graph of a quadratic function is U-shaped and it is called a PARABOLA.

  6. Parts of a parabola VERTEX:the highest or lowest point on the graph. Always a coordinate pair. Lies on the axis of symmetry X-value of vertex is the same value as the line of symmetry Max if open down Min if open up

  7. Parts of a parabola AXIS OF SYMMETRY: vertical line (x = a) that divides the parabola into two symmetrical parts.

  8. Ex 3: Vertex: ____ Axis of symmetry: _____ X-intercept:_____ Y-intercept:_____

  9. Try Some! Identify the vertex, axis of symmetry, x intercept and y intercept.

  10. Try Some! Identify the vertex, axis of symmetry, x intercept and y intercept.

  11. Complete the investigation: Pairs will display their work under the doc cam. Make sure your work is neat!!!
