Question

PLEASE HELP! 40 POINTS!!!

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 the x value of a function/ graph.

The horizontal line would be the X value. The line starts at 30 and ends at 60,

So the answer would be:

C. 30 ≤ x ≤ 60, or x is from 30 to 60
