Of course, quadratic functions, or second degree polynomial functions, graph as parabolas. Since we will be graphing these functions on the x, y coordinate axes, we can express the parabolas this way: y = 1.5x 2 - 9x + 11.5 Determining the nature of the function you are graphing. Jump to: Linear (straight lines), Quadratic (parabolas), Absolute value Remember that the high school curriculum is designed so that even relatively stupid students can get decent grades, provided that they spend time doing homework and read textbooks. Graphing quadratics We can use completing the square to graph quadratic polynomials. If p(x)=ax2 +bx+c, then p(x)=a � x+ b 2a � 2 +c− b2 4a. Therefore, the graph of p(x)=ax2 + bx + c is obtained by shifting the graph of ax2 horizontally by b 2a, and vertically by c− b2 4a. Example. To graph −3x2 +5x−2, first complete the square to ... Instead of plotting a graph we can use Algebra: Example: You versus Horse. Let us solve it using Algebra. The system of equations is: d = 0.2t; d = 0.5(t-6) In this case it seems easiest to set them equal to each other: d = 0.2t = 0.5(t-6)
