Worth 49 points the 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)

A:

1 - The bus increases it's journey.

2 - Journey is always the same

3 - The bus decreases it's journey.

4 - Journey is always the same.

5 - Journey decreases a lot.

B:

The function icreases in the part that show a line with a curve going up, decreases in the part that shows a line with a curve going down and the function is consntant when the line is straight and horizontal.

C:

Some parts are linear (the ones that are straight and don't contain any slopes).

Some parts are non-linear (the ones that aren't straight and contian slopes).

Hope it helped,

Happy homework/ study/ exam!
