Question

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.

Which statement best describes the domain of the function represented in the graph?

A.5 ≤ x ≤ 60, or x is from 5 to 60

B.5 ≤ x ≤ 30, or x is from 5 to 30 

C.30 ≤ x ≤ 60, or x is from 30 to 60 

D.0 ≤ x ≤ 30, or x is from 0 to 30

Answer 1

The domain is values on the x-axis which relate to your problem while the range is values on the y-axis. I cannot see your graph, but using the data points described (30,5) and (60,5), we can figure out what both are. The x-values in your points are 30 and 60, so those should allow you to find your domain.
