Inequalities Symbols and Boundary Points

When graphing the solutions to "OR" inequalities, the shading always

• connects the two boundary points

• points in opposite directions and never crosses.

• points toward each other and crosses

• points opposite, but sometimes crosses.

-2 < x - 9 < 3

• x < 12

• 7 < x

• 7 < x < 12

3x-4< -13 or 7x+1> 22

• All Real numbers

•   x>3   and x>-9

• The answer is not listed

• x<-3   or x>3

x+2<-4 or -5x<-15

• -6<x<3

• x<-3 and x>6

• x<-6 or x>3

• No Solution

What inequality is graphed?

• x > 2 and x < 4

• 2 ≤ x ≤ 4

• x > 2 or x < 4

• x ≥ 2 or x ≤ 4

Consider the function y < 2x+3. Which is true?

• The line would be solid with shading above.

• The line would be dashed with shading above.

• The line would be solid with shading below.

• The line would be dashed with shading below.
