Question

3 QUESTIONS!

1 and 2 are the same depth and time graph
Question 3 is the distance and time graph (aka the last one)

1. Mario measured the depth of the river as a function of time and graphed his findings. Use this graph to answer the following question.

What is/are the interval(s) where the graph is increasing?

A. (2, 10)


B. (2, 4) U (4, 10)


C. (9, 22)


D. (0, 3) U (7, 9)



2. Mario measured the depth of the river as a function of time and graphed his findings. Use this graph to answer the following question.

What is the minimum depth of the river that Mario measured?


A. 1 meter


B. 9 minutes


C. 22 minutes


D. 10 meters


3. The following graph shows Taylor's journey home. The y-axis is the distance Taylor is from home. The x-axis shows the time of his journey. According to the graph, what is the farthest distance Taylor was from his home? (Find the Maximum)


A. 18 meters


B. 8 meters


C. 10 meters


D. 18 minutes

Answer 1

Explanation:

1.

you know the meaning of "increasing" ? it means to grow bigger, normally to go up.

the only intervals where the depth gets bigger (the river gets deeper) is between time (minutes) 0 and 3, and then between time (minutes) 7 and 9.

so, the correct answer is D.

2.

the minimum recorded depth (the lowest level measured) of the river is 1 (meter) at 22 minutes (the end of the observation).

3.

the maximum distance (the farthest away) from home was 10 meters at 7 minutes into his trip home.

it seems at that time he was distracted or had to go around some obstacle.
