Notation Problem 3

Incorrect!

Tutorial to help us answer problem 3.

 

The set {x| -8 < x ≤ 5} consists of all real numbers x less than or equal to 5, but greater than -8.

We can rewrite this set using interval notation as (-8, 5] since the open bracket parenthesis, i.e. (, means "do not include" and the closed bracket,i.e. ], means "include."
