Fundamental Formula
$$f(x) = a x^2 + b x + c$$
Standard quadratic/polynomial formRoot / Zero Formula
$$x = rac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
Quadratic discriminant solverRate of Change / Slope
$$m = rac{y_2 - y_1}{x_2 - x_1} = \lim_{\Delta x o 0} rac{\Delta y}{\Delta x}$$
Linear and instantaneous slopeSummation / Series
