Today, students studied the graph of quadratic equations y=ax^2+bx+c and understand the feature of the graphs in the shape of “parabola”, such as, leading coefficient “a” determines the graph open direction, upward or downward, vertex point represents the minimum point … Continue reading →

Today, students worked on the graphing method to solve the quadratic equations, understanding the relation of quadratic function y=ax^2+bx+c and quadratic equation, ax^2+bx+c=0. First of all, students learned to plot the quadratic functions, mostly using traditional way, connecting some ordered … Continue reading →
