HL 2.1 – Quadratic functions
SL 2.6: The quadratic function f(x)=ax^2+bx+c : its graph (called a parabola), y -intercept (0,c) . Axis of symmetry. The form f(x)=a(x-p)(x-q) , x -intercepts (p,0) and (q,0) . The form f(x)=a(x-h)^2+k , vertex (h,k) You have probably encountered quadratic functions before, and perhaps seen some common applications such as the falling object model, projectile motion or optimisation exercises. In this course,...
