what is the answer to this in interval notation -8<x<1

Question

need help

Answer 1

In interval notation

-8<x<1 is (-8, 1)

 

The parenthesis indicates the endpoint is NOT 

included.  If the interval includes the endpoint

we use a bracket [ or ] instead of parnthesis ( or )

 

Example:  -8 ≤ x < 1

This includes the endpoint -8 so interval notation is

[-8, 1)

Answer 2

It is all the numbers greater than -8 and less than 1.
