What is the degree of the product 3x(x+2)

Part A : ∵ The slope of a line having endpoints and is,

By the given graph,

Line P has endpoints (0,0) and (2,6),

Slope of line P,

Line Q has endpoints (2,6) and (3,6),

Slope of line Q,

Line R has endpoints (3,6) and (5,0),

Hence, the graph is not linear.

Part B :

In the segments P, slope is positive,

So, graph is increasing,

In the segment Q, slope is 0,

So, the graph is constant,

In the segment R, slope is negative,

So, the graph is decreasing.

Part C :

Motion is the change in the position of an object with respect to time,

By the given graph ant is moving away from the hole for 2 seconds then stopped for 3 seconds, finally it moves back to the hole for 2 seconds.
