Seven-year-old students at an elementary school were given a 10-yard head start in a race. the graph shows how far the average student ran in 30 seconds. a line graph with distance, in yards, on the x axis and age of runner on the y axis. the x axis has a scale from 0 to 80 in increments of 10. the y axis has a scale of 0 to 8 in increments of 2. a straight line connecting 10, 7 and 60, 7 is drawn. which statement best describes the domain of the function represented in the graph? 10 ≤ x ≤ 60, or x is from 10 to 60 7 ≤ x ≤ 60, or x is from 7 to 60 7 ≤ x ≤ 10, or x is from 7 to 10 0 ≤ x ≤ 10, or x is from 0 to 10
