Chapter 5.6 & 5.7
You will use these skills in .....
You will be able to:
Find vertex
Sketch quadratic graphs by GDC and by hand using a table
Find equation of quadratic function, represent in standard form and root form
Key Vocabulary:
Vertex, parabola, intercepts, turning point, max and min values, standard form, root form
***Play around with the vertex graphing image to seeeffect of changing a,b,c values: https://www.mathsisfun.com/definitions/vertex-parabola-.html
Notes:
The vertex is theturning point, min/max value along the parabola
Need to know 2 forms of representing quadratic equations - root form and standard form
Standard form is the quadratic expanded and simplified
Root form has brackets and in factorised mode
