The weights and heights of six mathematics students are given in the following table: Weight (in pounds) Height (in centimeters) 165 172 123 157 212 183 175 178 165 163 147 167 State whether height is a function of weight for the six students and explain.

A relation is a function when each input has exactly one output. Here, the weight 165 pounds is paired with two different heights, 172 cm and 163 cm. Therefore, height is not a function of weight, so the correct choice is “No, height is not a function of weight because two students weigh 165 pounds but have different heights.”
