Answer 1

Answer:

Step-by-step explanation:

Part A

x-intercepts of the graph represent the value of goods at which profit of of the company is zero → Break even of the company

Maximum value of the graph represents the maximum profit of the company at certain price of the goods.

Part B

Interval in which the function is increasing → x = 0 to x = $3

Profit of the company increases when price of the goods increase from 0 to 3.

Interval in which the function is decreasing → x = $3 to x = $6

Profit of the company decreases when the price of the goods increases from 3 to 6.

Part C

Average rate of change of the function from x = a and x = b,

= $\frac{f(b)-f(a)}{b-a}$

By applying the same rule,

Average rate of change of the function between x = 1 and x = 3

= $\frac{120-60}{3-1}$

= $\frac{60}{2}$

= 30
