The graphs of quadratic inequalities follow the same general relationship. Greater than inequalities are the region above the equation's graph and less than inequalities are made up by the region underneath the graph of the equation.
What is the solution of a quadratic inequality?
Below, you will learn a formula for solving quadratic inequalities. First, it's important to try to understand what a quadratic inequality is and what its solution is. So let us explore a graphical solution for a quadratic inequality.
We will examine the quadratic inequality $$ y > x^2 -1 $$ .
