Question

How do you the interval notation, (-∞, 6]? Is it "from negative infinity to 6" or "from 6 to negative infinity"?

Answer 1

from negative infinity to 6, i believe. means from anything smaller than -6 to -6

Answer 2

"from minus infinity to 6" is one way

Answer 3

Don't you have to also mention that the 6 is included and the -infinity is not included?

Answer 4

or "from negative infinity to six"
or " all numbers less than or equal to six"

Answer 5

yes, 6 is inclusive :))

Answer 6

I think "all real numbers less than or equal to six" might be the best way to say it

Answer 7

ops misread 6 with -6. sorry
