Describe the function over each part of its domain. state whether it is constant, increasing, or decreasing, and state the slope over each part.

 domain (0,12000) is constant and slope =0

domain (12000, 38000) is decreasing and slope = negative

Step-by-step explanation:

We analyze the given graph

From x=0  to x=12,000 the y values remains the same

the value of y is constant, there is no increase or decrease in y

So from x=0 to x= 12000, the graph is cost is constant

Hence slope =0

 domain (0,12000) is constant and slope =0

From x=12,000  to x=38,000 the y values is decreasing

For decreasing y values the slope is negative

So we can say the slope is negative

domain (12000, 38000) is decreasing and slope = negative
