Advice

The closed (square) brackets in $[\var{a},\var{b}]$ signify that those endpoints are included in the interval (as well as all real numbers between them). This is known as the closed interval $[\var{a},\var{b}]$.

When we graph the interval, endpoints that are not included are represented by circles that are not filled in, whereas, endpoints that are included are represented by circles that are filled in.
