Grade 9 Math | Quadratic Relations and Functions in Real Life Situations Second term (Term 2) Week 6

What is quadratic relations? What is quadratic functions? What are real life situations that ca be modelled by quadratic relations or functions? What is the graph of quadratic functions? What are the different parts of quadratic functions? What are examples of quadratic functions? The learning competency of this lesson is represent real-life situations that can be modelled using quadratic relationships. The learning objectives are recall what relations and functions are; Identify and define quadratic functions; Identify the values of a, b, and c in a given quadratic function; Describe the opening and the vertex of a parabola; Model real-life situations using quadratic functions. This video lesson discussed and presents definition and examples of quadratic functions and relations. It also discussed how to determine values of a, b and c of a given quadratic functions. It discussed how to determine if equation is quadratic function of not. This lesson is under the revised K to 10 curriculum of Grade 9 mathematics. #Term2 #Secondterm #Week6 #RevisedKto10 #Math9 #Grade9mathematics #Quadraticfunction #Quadraticrelations #Real-lifesituationsaboutfunctions
