Graphing Quadratic Functions: Introduction. Graphing Quadratic Functions (page 1 of 4) Sections: Introduction, The meaning of the leading coefficient / The vertex, Examples The general technique for graphing quadratics is the same as for graphing linear equations. However, since quadratics graph as curvy lines (called "parabolas"), rather than the straight lines generated by linear equations, there are some additional considerations. The most basic quadratic is y = x2. When you graphed straight lines, you only needed two points to graph your line, though you generally plotted three or more points just to be on the safe side. He got the graph wrong. That last point has a rather large y-value, so you decide that you won't bother drawing your graph large enough to plot it. Graphing Quadratic Equations. A Quadratic Equation in Standard Form (a, b, and c can have any value, except that a can't be 0.) Here is an example: Graphing You can graph a Quadratic Equation using the Function Grapher, but to really understand what is going on, you can make the graph yourself. Read On! How to Graph a Quadratic Equation: 10 Steps. Edit Article Community Q&A When graphed, quadratic equations of the form ax2 + bx + c or a(x - h)2 + k give a smooth U-shaped or a reverse U-shaped curve called a parabola.
