Answer 2

i got y/y<7 for the set

Answer 3

Interval notation uses the smallest and larges value of the interval separated by a comma.
Then you use a square bracket to include the value of parentheses to not include the value. With infinity and negative infinity, parentheses are used.

Answer 4

For example, to mean all numbers from 5 to 8, including 5 and 8, you'd write:
[5, 8]

If it numbers greater than 5 and less than 8, then it's
(5, 8)

If you want to show the interval from 5 to infinity, then it's
\([5, \infty)\)

All real numbers is
\((- \infty, \infty) \)

Answer 5

I think I get it now :)

Answer 6

So, I got y/y>7 for the set notation. Yes?

Answer 7

Set: {the set of all real x, such that x > 7}
There are proper math symbols for the above.

Interval: \((7, \infty)\)
