Answer 4

any number less than 2 is include -1,-1000000, - infinite

Answer 5

let theres two numbers a,and b are in the intervals then\[(a,b)=open ~interval=a<x<b\\ [a,b]=closed ~interval=a \le x \le b\]

Answer 6

so A it should be the answer

Answer 7

Thank you!!! :)

Answer 8

yes because 2 is > than x
and if u draw it in a number line then it will go endlessly to negetive infinity
