In this math tutorial I will show you how to sketch a quadratic function, find the axis of symmetry, determine the y-intercepts and find the zeros or x-intercepts. To find the x-intercepts we use such ...

Two lines, each determined by two points, as Euclid predicted, are tangent to a parabola. Point A is located at ( 4, 20 ), point B is located at ( 14, 25 ) and intersection C is at ( 9, 10 ). Given ...
