i just started pre-calc, we were not taught anything and yet given an assignment. i am sure these are very basic and perhaps dumb problems to be stuck on, but i don't get what to do.(adsbygoogle = window.adsbygoogle || []).push({});

"express the interval using inequalities, and give a sketch of the numbers in the interval."

1) [-3,-1]

2) [*rad*5, -*rad*2]

there is more, but if someone can jsut explain what i do that'd be great!
