Step 1When writing intervals as inequalities we need to remember that parentheses, like,             (      a      ,      b      )       are equivalent to strict inequalities, so             (      a      ,      b      )        →    a    &amp;lt;    x    &amp;lt;    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.)
