Can someone solve {x|-6<x<-3} using interval notation and explain how to graph it on a number line?

Answer 1

Interval notation uses parenthesis and/or brackets to express a given domain or range of values. In this case, the values of x are all values between -6 and -3, not including the boundaries. Interval notation would use parenthesis to exclude the boundaries and will be written (-6, -3).
