Question

he graph represents the journey of a bus from the bus stop to different locations: The title for the graph is Bus Journey. The label on the y-axis is Distance in miles, and the label on the x-axis is Time in hours. The graph shows 5 parts. The part labeled 1 is a smooth curve going up from the origin. The part labeled 2 is a straight horizontal line. The part labeled 3 is a smooth curve going down. The part labeled 4 is a straight horizontal line. The part labeled 5 is a smooth curve going down that touches the x-axis. Part A: Use complete sentences to describe the motion of the bus in parts 1, 2, 3, 4, and 5 of the journey. (4 points) Part B: In which parts of the graph is the function increasing, decreasing, and constant? (4 points) Part C: Is the graph linear or non-linear? Explain your answer. (2 points)

Answer 1

Part 1) Smooth curve going up the Origin, means, the distance of the bus is increasing with increase in time. In other words, Bus is in the motion.

Part 2) Distance is constant here & Bus is not moving at all.

Part 3) Distance is decreasing, means bus in moving in opposite direction, and it is said to be the negative displacement.

Part 4) Again, The Distance is constant here & Bus is not moving at all.

Part 5) Here, Displacement is negative, which means bus is moving in the opposite direction and reached the starting point.

Part B) It is Increasing at: Part 1
It is decreasing at: Part 3 & 5
It is constant at: Part 2 & 4

C.) Graph is non-linear, as it shows deviation through the complete journey of the Bus.

Hope this helps!

Answer 2

Part A: 

Part 1: In part 1, the bus is slowly traveling upwards.

Part 2: In part 2, the bus looks like it has completely stopped.

Part 3: In part 3, the bus is slowly traveling downwards.

Part 4: In part 4, the bus looks like it has completely stopped again.

Part 5: Finally, in part 5, the bus has arrived at it's final destination.

Part B:

Part 1 is increasing

Part 2 is constant

Part 3 is increasing (?)

Part 4 is constant

Part 5 is decreasing

Part C:

The graph is not linear. This is because it's curved, and when we are talking about linear, the line has to be completely straight.
