The given diagram shows that the wormfish are found at a depth between feet and feet. If we let represent the depth at which wormfishes are found, it follows that must be greater than or equal to and must be less than or equal to To graph these inequalities, we will place a closed circle on both and because can equal these values. The solution set is shaded as the region between them.
