Graph of Quadradic Equation in standard form
Author: Robert Laurie

Using the sliders you can change the coefficients of the quadratic equation in standard form:  f(x) = a x² + b x + c

a = 1 (slider from -10 to 10, step 0.2)
b = -4 (slider from -10 to 10, step 0.2)
c = 3 (slider from -10 to 10, step 0.2)
f(x) = (a * x^(2)) + (b * x) + c
text1: "f(x) = " + a + " x² + " + b + "x + " + c
