Finding A Quadratic Function Using
Gbogbo ọrọ náà
A quadratic graph is a smooth U-shaped curve called a parabola, and it is completely fixed by just a few key pieces of information. Tell me its vertex and one more point, or where it crosses the x-axis and one more point, and the whole curve is determined. Working backwards from features to the equation is a powerful and very practical skill.
In this lesson you will find the equation of a quadratic from given information: from its vertex and another point, from its x-intercepts and a point, and from its vertex or x-intercepts in the simple case where the leading coefficient is one. With a couple of standard forms, these problems become straightforward.
