The graph below shows a company's profit f(x), in dollars, depending on the price of pens x, in dollars, 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? (5 points)
Part B: If at one time the profit of the company was at least $60, what domain could possibly produce this profit? (2 points)
Part C: What is an approximate average rate of change of the graph from x = 3 to x = 5, and what does this rate represent? (3 points)

help!!!!

- phi

how far did you get ?

- OregonDuck

we need help starting

- phi

graph below shows profit f(x),
x is the price of pens
when the price of pens is 0, what is the profit?
any idea ?

- OregonDuck

none

- phi

put your finger on the x-axis at x=0
where is the graph (i.e. what is the y-value (how high above the x-axis) is the curve?

- phi

confused by what I am asking?

- HelloKitty17

yea

- phi

do you see the parabola? it starts low on the left, goes up to a peak and goes down.
as you move sideways to the right, the x-value gets bigger.

- HelloKitty17

yes I see it

- OregonDuck

120

- phi

at each x value the parabola has a height (y value)
for example, at x= 3 the parabola is at y=120
see that?

- OregonDuck

yes that i what i just said

- phi

if you read the problem they tell you x is the price of pens.
x=3 means the price of a pen is 3 (dollars?)
f(x) is the profit
the highest profit is 120 when the price of a pen is 3

- phi

that is part of the answer to part A
maximum value of the graph represent?
can you say what the maximum value represents ? (I just told you)

- OregonDuck

120

- phi

yes it is 120
but what does the peak mean? f(x) is the profit. the peak is where you make the most profit.

- phi

that is the answer to what does the maximum value of the graph represent?

- phi

now
What do the x-intercepts mean?
the x-intercepts are where the parabola crosses the x-axis (i.e. where y=0)
what two x values are where the parabola is at y=0 ?
any idea?
