Question

Six year old students at an elementary school we’re giving a 20 yard Headstart in a race the graph shows how far the average student run in 30 seconds

Which statement best describes the domain of the function represented in the graph
A. 6 B. 6 C. 0 D. 20 < x< 60, or x is from 20 to 60

Answer 1

The answer is going to be (D)

Answer 2

Option D. 20 < x < 60 or x is from 20 to 60

Explanation:

When a function is graphed, x coordinates of the points on graph show "domain" and y coordinates of the points represent "range"

In the graph attached domain of the function will lie from 20 to 60.

It can be shown in the form of

20 < x < 60 or (20,60)

which is the interval form of domain.

Therefore, option D is the answer.
