Question

This graph shows the movement of Kareem as he travels from his house to different locations throughout his town.

a) What is the domain of this function?
_ ≤ x ≤ _

b) What is the range of this function?
_ ≤ y ≤ _

c) According to the graph, what is the total time that Kareem is not moving?
__ hours

(THE ___'S represent the blank space that needs filled in!)

Answer 1

a) Domain 0 ≤ x ≤ 4

B) Range 0 ≤y ≤ 2

C) 1.5 hours.

Sorry, I do not know what they are looking for in the blank

Explanation:

The domain is the x values. If you look at the numbers on the horizontal axis. It starts at zero and goes to 4.

The range is the y values. If you look at the number on the vertical axis. It starts at zero and goes to 2.

He is not moving when you see the flat, horizontal lines. That is from (1,2) to (2,2) That is a time of 1 hour. The x values tell us the time. The y tells us the distance. There is also no movement at (3, .5) and (3.5, .5)
This is half of an hour. The total would be 1.5 hours.
