Solving Double Inequalities

Inequalities : Meaning of Inequalities Symbols <   means Less than ≤     means Less than or equal to >   means Greater than ≥     means Greater than or equal to For ( single ) inequalities, treat the inequalities symbols as "=" sign. The only difference is when you divide (or multiply) both sides by a negative number. Example :         -3x   <  15         -3x / (-3)   >   15 / (-3)           x  >  -5 Solving Double Inequalities : 

Sketching a quadratic curve or graph

Sketching Quadratic Curve Given a quadratic curve, you will need to let x=0 and then y=0, and to find the required coordinates of points the graph intercept with the x-axis and y-axis. By looking at the cooefficient of the x-square term, a>0, the curve is opened upward (smiley face), when a<0, the curve is opened downward (sad face). Find the Mid-point of the x-intercept, substituding x value into equation, you will get the coordinates of the minimum or maximum point of the graph.
