This past week in Pre Calculus 11 we worked on unit 5: Graphing Inequalities and Systems of Equations. This week I learned how to graph inequalities and find the area that the possible answers could be that would make the equation true.

Any point in the shaded part would make this a true statement.

*Key points to remember:

When the sign is greater than or less than the line on the graph is dashed and if the sign is greater than or equal to or less than or equal to the line on the graph is solid.

Any point on the graph could be chosen for step 3 as the test point as long as it is not on the parabola.
