interval notation-need sets?

Question

write the set using interval notation.

{x | -6 less than or equal to x < 4}

Answer 1

I think that you want x element of [-6,4)

You wanted closed on the left and open on the right, is that true?

Just remember that for intervals:
open ( )
closed [ ]

And you can match them up: [-6,4)

Answer 2

f(x) is defined for all real numbers so the area is (-infinity,+infinity). The smallest fee a danger for /x/ is 0 which provides a value of -7 for f(x). larger values for x (the two detrimental or beneficial) provide values larger than -7 as much as +infinity. the form is subsequently [-7, +infinity). i'm no longer sparkling on the Set Builder notation so i'm uncertain what to respond to.

Answer 3

{x | -6 less than or equal to x < 4}
= [-6, 4)
