Question

In interval notation the set of all real numbers greater than -6 and less that or equal 14 is represented by?

Answer 1

(-6,14]

Explanation:

We are given that x>-6 and that x</=14

When you put a number in parentheses that means that the number is not included. Numbers in brackets mean that the number is included. You know that its included if it's a less/greater than or equal to sign

Basically, the answer is saying that all numbers between, but not including, -6 and 14 are being represented.
