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
