Answer 3

the x intercepts show where the company makes no profit...

the maximum is the max profit made

look at the graph as decide between which values a tangent would have a positive slope... and between which values it has a negative slope.

(b) go up the y axis to 220

then read off the x values.... so between those values you make at least 220 profit..
you'll need to write this using inequalities.

(c) find the points (2, f(2)) and (4, f(4)) and then calculate the slope of the segment joining the 2 points

Answer 4

@ranga could you help me with part C

Answer 5

I just need part C

Answer 6

Average rate of change from x = a to x = b is: { f(b) - f(a) } / (b - a)

Answer 7

Average rate of change from x = 2 to x = 4 is: { f(4) - f(2) } / (4 - 2) =
(0 - 300) / (2) = -150.

Answer 8

The meaning of average rate of change of -150 from x = 2 to x = 4 is:
The profit of the company declines by $150 for every dollar increase in the unit price of notebook between $2 to $4.
