His jump could be graphed on a set of axes where x represents time and y represents distance above or below sea level. The domain for this graph is best represented using a set of1)integers3)real numbers2)positive integers4)positive real numbers2. A grocery store sells packages of beef. The function represents the cost, in dollars, of a package of beef weighing w pounds. The most appropriate domain for this function would be1)integers3)positive integers2)rational numbers4)positive rational numbers3. Jennifer goes to the ice cream truck to buy x ice cream cones.
