Hi,

Express the set of numbers shown on the number line in set builder notation

The number line did not make the trip.

Check the shaded part of the number line and whether there is open or closed circles on either end.. open circle indicates that number is NOT included in the set.. 

for ex: 

 a. {xER|x≥-7 or x<5}  

would be shaded from -7 to 5 with a closed circle on -7 and open circle on 5

NOte:  b & c do not have the right end }

Wish You the Best in your Studies.
