Graphing systems of quadratic inequalities

A system of inequalities means that there are more than two inequalities we need to look at to answer the questions. One way to solve this kind of questions is by graphing the systems of quadratic inequalities out.

Basic Concepts: Quadratic function in general form:

y = ax^2 + bx+c

, Quadratic function in vertex form: y =

a(x-p)^2 + q

, Graphing parabolas for given quadratic functions, System of quadratic-quadratic equations

Solve the system:
$y$ > $\frac{1}{3}{x^2} - \frac{2}{3}x - \frac{8}{3}$
$y \le - {x^2} - 4x$
