what if the endpoints are not exactly placed in a whole number, how should i write it in interval notation? should i round it off or should i just keep it as it is with a decimal?

A note for the graph on the left, if it curves you pick the highest point of the curve, not the dot, according to my professor and the work she's given us.

[johnzrock]

At 2:45 you write -5 < y but it should be -5 > y
