i got y/y<7 for the set

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.

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 $$(- \infty, \infty)$$

I think I get it now :)

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

Set: {the set of all real x, such that x > 7} There are proper math symbols for the above. Interval: $$(7, \infty)$$
