Five-year-old students at an elementary school were given a 30-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 6 in increments of 2. A straight line connecting 30, 5 and 60, 5 is drawn. Which statement best describes the domain of the function represented in the graph? 5 x 60, or x is from 5 to 60 5 x 30, or x is from 5 to 30 30 x 60, or x is from 30 to 60 0 x 30, or x is from 0 to 30
