The number line shows the solutions of the given compound inequality. The solutions are:

x > 2 o r × < − 2 x>2\ or\ \times<-2 x > 2 o r × < − 2

x ≤ − 6 o r x ≥ − 5 x\le-6\ or\ x\ge-5 x ≤ − 6 o r x ≥ − 5

x ≤ − 2 a n d x > 2 x\le-2\ and\ x>2 x ≤ − 2 a n d x > 2

x > − 2 a n d x < 2 x>-2\ and\ x<2 x > − 2 a n d x < 2

How can you tell whether a parabola is facing up or facing down by looking at the equation?

The value of "a" tells you the direction of the opening.
