[tex]{ \large{ \underline{ \overline{ \boxed{ \blue{\tt { \: Quadratic\ Inequalities\ in\ One\ Variable}}}}}}}[/tex]
- is when we have two expressions that are not equal to one another, we can relate the expressions by the use of an inequality sign.

B. Describe and correct the error in graphing y > x² + 2x in the following figures
- The graph of y = x 2 moves to the right by 1
-
The graph of y = x 2 moves down by 1
Correction: y = [tex]\large\tt x^{2}[/tex]
