Grade 9 & 10 math tutorial on quadratic equations & parabolas for SAT, Math Kangaroo, and AMC10 Preparation.
The equation of a parabola in vertex form has one of the following 2 forms:
If the parabola is a vertical parabola, it will take the vertical form of the equation, and if the parabola is a horizontal parabola, it will take the horizontal form of the equation. More...
The graph of a quadratic function y = ax2 + bx + c is called a parabola. The following graphs are two typical parabolas:
For the sake of explanation, we mark their x-intercepts by red dots, their y-intercepts by a pink dot, and the vertex of each parabola by a green dot: More...
