Question

Jeremy thinks that a person's height is a function of his or her shoe size. He records his classmates shoe sizes (x) and their heights (y), and graphs the function. Which choice would most likely be used to label the x-axis with shoe sizes? A) {...-3, -2.5, -2, -1.5, -1, -.5, 0, .5, 1, 1.5, 2, 2.5, 3, ...} B) {0, 1, 2, 3, 4, 5, ...} C) {4, 5, 6, 7, 8, ...} D) {4, 4.5, 5, 5.5, 6, ...}

Answer 1

d

Explanation:

the domain is the shoe size of each person. since he is talking about his classmates, 4 is a smallest shoe size. so the correct domain is {4, 4.5, 5, 5.5, 6, ...}

Answer 2

D i think because there is no negative shoe size and D seems more possible.
