Which one do you think is the right answer?

OpenStudy (anonymous):

Remember " [ " or " ] " means included or closed and " ( "or " ) "means not included, or open.

OpenStudy (anonymous):

So what would i put?

OpenStudy (anonymous):

Which one start with minimum -5?

OpenStudy (anonymous):

I think its a or b im just not sure

OpenStudy (anonymous):

but not equal -5

OpenStudy (anonymous):

Well if you look at the interval notation, it says greater than -5 and less than or equal to 4, so which 2 graphs can we eliminate?

OpenStudy (anonymous):

Yeah it's one of a or b and remember what I said about the brackets?

OpenStudy (anonymous):

If it's less than or equal to we use [ or ] , if it's strictly less than we use ( or )

OpenStudy (anonymous):

A?

OpenStudy (anonymous):

Perfect

OpenStudy (anonymous):

so when i type in numbers is (-5,4] ?

OpenStudy (anonymous):

Correct!

OpenStudy (anonymous):

Thank you everyone :)
