How to Graph the Intercept Form of a Parabola Lesson Summary Frequently Asked Questions How do you find the equation of a parabola in intercept form? Consider a parabola given by y = ax^2 + bx + c. Apply the quadratic formula, which gives the roots p and q. Then, the intercept form...
Graphing Parabolas Example – See board or Overhead. Parabola – the graph of the equation y=x2. Axis of Symmetry – the vertical line along which the graph of a parabola can be folded and yield the mirror of one side on the other side. Vertex – the point of a parabola where the ...
Anaxis of symmetry (also known as a line of symmetry) will divide the parabola into mirror images. Theline of symmetryis always a vertical line of the formx=n, wherenis a real number, and its axis of symmetry is the vertical linex=0. ...
The vertex of a quadratic function (which is in U shape) is where thefunctionhas a maximum value or a minimum value. Theaxis of symmetryof the quadratic function intersects the function (parabola) at the vertex. Quadratic Functions Formula ...
