Fro the graphs of the polynomial f(x) = x 2 2x 8, following observations can be drawn (i) The coefficient of x 2 in f(x) = x 2 2x 8 is 1 (a positive real number) and so the parabola opens upwards (ii) D = b 2 4ac = 4 32 = 36 >The graph of f(x) in this example is the graph of y = x 2 3 It is easy to generate points on the graph Choose a value for the first coordinate, then evaluate f at that number to find the second coordinate The following table shows several values for x and the function f evaluated at those numbers x 2 1 0 1 2 f(xCos(x^2) (x−3)(x3) Zooming and Recentering To zoom, use the zoom slider To the left zooms in, to the right zooms out When you let go of the slider it goes back to the middle so you can zoom more You can clickanddrag to move the graph around If you just clickandrelease (without moving), then the spot you clicked on
