Question

please help!!!! :( :( :/ :/


the graph below shows a company's profit f(x) in dollars, depending on the prices of pens x, being sold by the company.

part a) what do the x intercepts and maximum value of the graph represent?what are the intervals where the function is increasing and decreasing and what do they represent about the sale and profit?
part b)if at one time the profit of the company was at least 60 dollars, what domain could possible produce this profit?
c)what is an approximate average rate of change of the graph from x=3 to x=5 and what does this rate represent?

Answer 1

You'll need to include the graph.

Answer 3

I'm not a math genius. Try reaching out to some ambassadors or moderators. c:

Answer 4

part a) what do the x intercepts and maximum value of the graph represent?
What do you think? The horizontal scale represents the selling price and the vertical scale represents the profit. What is happening at (0,0)? at (6,0)? At (3,0)?

Answer 5

the line is crossing the points?

Answer 6

Actually, it's a GRAPH (not a line) crossing the x-axis.

What does "profit" mean? Profit is represented by the vertical axis.
What does "quantity" mean? Quantity is repr. by the horizontal axis.

How would you interpret the meaning of (0,0) on this graph?

@bangbang559 : I have been trying to help you by giving you hints, reviewing definitions and the like. I will never just be giving you answers. I need and expect your involvement. Even if it turns out to be wrong, write down your thoughts, show your first steps, ask for clarification.... please do something. You'd learn so much more this way.
If you want to continue with part a, respond in some way, any way....please say something related to this problem.
If you want to do part b, please get started now. What do you already know? What do you need / want to know to be able to solve this problem? Please get involved.

Answer 9

I don't expect for you to just give me the answer but I still don't understand how to do part a, I'm sorry I am terrible at math and gets really confused easily @mathmale

Answer 10

"part a) what do the x intercepts and maximum value of the graph represent?"
If x=0, that means that if the price of the pens is set at zero (0), the resulting profit is zero (0). If x=6, meaning that the price of one pen is $6, then the profit is again zero (0). But if x=3, meaning that the price of each pen is $3, then the company's profit is at a maximum, and that maximum profit is $120 (read from the graph, at the vertex of the graph).

Answer 11

okay I sorta understand

Answer 12

@bangbang559 : Can you suggest how we could best work together in such a way that you can both understand and solve these problems here and in the future?

You've responded, "okay i sorta understand." What would it take for you to fully understand what these problems are asking you for and how to find that?

Have you worked with the concept, "profit," before?

I need for you to tell me as best you can what you DO understand of this problem and what you DO NOT understand Is it the vocabulary that's unclear?

Once more: x, on the horizontal axis, represents the selling price of pens. From the graph, we can see that this price ranges from zero to $6. y, on the vertical axis, represents the profit derived from selling these pens at price x. You see (or should be able to see) that if the selling price is zero (0), the profit is also zero. If, on the other hand, the selling price is $6, people will find the pens too expensive and won't buy any, and so the profit will again be zero. But if the selling price is set at $3, the seller will sell the maximum number of pens and then will take in the maximum profit.

Answer 13

Do you know what an "interval" is in Math? If you'll look at your graph again, you'll see that if x increases from zero (0) to 3, the profit continues to increase. However, from 3 to 6, the profit decreases all the way to zero again. OK with that?
