Question

how to write an inequality in set notation describing a range of temperatures (t).

say if the range is from 2 to 100

would i write the set notation as:

{ 100 > t > 2 }

is that what set notation is? putting the inequality in the brackets?

please help

Answer 1

2 < t < 100 --- better.

Or {t / 2 < t < 100}

Answer 2

almost :

{2 <= t <= 100}

that <= sign is written with a < and one extra line parallel with the underside of the <

set notation is describing with mathematical symbols what the "range" of the set is.

Answer 3

2 <= t <= 100

:o)

Answer 4

2 < t < 100
