The graph represents the journey of a bus from the bus stop to different locations: (see attachment) part a: use complete sentences to describe the motion of the bus in parts 1, 2, 3, 4, and 5 of the journey. part b: in which parts of the graph is the function increasing, decreasing, and constant? part c: is the graph linear or non-linear? explain your answer.

Step-by-step explanation:

Part A.

In part 1, the bus drives pretty linearly.

In part 2, the bus is at a stop.

In part 3, the bus drives much faster, as the slope is much larger.

In part 4, the bus is at a stop.

In part 5, the bus comes back to its starting point. 

Part B. The bus is increasing in parts 1 and 3, decreasing in part 5, and at a constant at parts 2 and 4. 

Part C. The graph is non-linear, as the slope is not at a constant.

Hope this helps

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
