Step 1
When writing intervals as inequalities we need to remember that parentheses, like, ( a , b ) are equivalent to strict inequalities, so ( a , b ) a < x < b Brackets, like [ a , b ] are equivalent to inclusive inequalities, so [ a , b ] a x b
On a number line put 1 and 2.
Put open circles at 1 and at 2.
Shade the region of between the circles.
(Not sure how to conveniently show that on here.)
