represent the values of x in interval notation: x can be any real number between -8 and -6 or any real number greater than or equal to 29

Answer 1

(-8,-6) means any number between -8 and -6, but not including -8 or -6

if you want to include the end points, use brackets

[-8,-6]

x > or = 29 in interval notation is [29, infinity)

the bracket means you include 29 in the interval. since infinity is not a real number, just a limit, you use a closed parentheses, not a bracket
