Amedicine is known to decompose and become ineffective if its temperature ever reaches 103 degrees fahrenheit or more. write an interval to represent the temperatures (in degrees fahrenheit) at which the medicine is ineffective.

Interval = [103,∞)

Explanation :

A medicine become ineffective if its temperature ever reaches 103 degrees Fahrenheit or more .

So, Interval becomes [103,∞)

i.e. semi-open or semi-closed interval as it includes

So, we used closed brackets i.e. square brackets and

For '∞' we always use open brackets only.
