(AS 2.2) Slide 2: Last year for graphs (mostly achieved) (tended to be Merit/Excellence) Slide 3: THIS year.... Its own topic (Co-ordinate Geometry) Mostly at achieved level Slide 4: Equation types unfactorised, but simple Slide 5: Equation types PARTIALLY factorised Slide 6: Equation types FULLY factorised e.g. y = (x+2)(x-4) Slide 7: Equation types UN-factorised Slide 8: What do you do? Slide 9: Firstly, know how to sketch the basic shape. Slide 10: Equation types unfactorised, but simple Draw the basic shape. Vertex will just be higher or lower. Slide 12: Equation types unfactorised, but simple Draw the basic shape. Multiply the vertical distances by 3 Slide 14: Equation types PARTIALLY factorised Draw the basic shape Use your knowledge of TRANSFORMATIONS to know where to put the vertex. Slide 16: Equation types FULLY factorised Find the x intercepts (what makes y = 0) Find the vertex (halfway between x int.) Find the y intercept (by substituting x = 0) e.g. y = (x+2)(x-4) Slide 17: y = (x+2)(x-4) Slide 18: Equation types UN-factorised Factorise Or partially factorise (by completing the square) Slide 19: If in doubt... Make a table and plot the points! You do not have the permission to view this presentation. In order to view it, please contact the author of the presentation.
