Question

an office building has 8 floors above the ground. on a line graph that models the average number of times the elevator stops on each floor each day, which values will be the x - coordinates? a d = {1, 2, 3, 4, 5, 6, 7, 8} b d = {0, 1, 2, 3, 4, 5, 6, 7} c d = {0, 1, 2, 3, 4, 5, 6, 7, 8} d d = {-1, -2, -3, -4, -5, -6, -7, -8}

Explanation:

Step1: Analyze the floor numbering

In an office building, the floors above the ground start from floor \(0\) (ground floor) up to floor \(8\).

Step2: Determine the domain for \(x -\)coordinates

The \(x -\)coordinates (domain) should represent the floors. Since there are \(8\) floors above the ground (including the ground floor), the values are \(0,1,2,3,4,5,6,7,8\).

Answer:

C. \(D = \{0,1,2,3,4,5,6,7,8\}\)
