Medal and fan and testimony. Please help! The graph below shows a company's profit f(x), in dollars, depending on the price of pencils 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 $100, what domain could possibly produce this profit? (2 points) Part C: What is an approximate average rate of change of the graph from x = 2 to x = 5, and what does this rate represent? (3 points)
@IMStuck @lacrosseplayer22 @KatKatJV @ChihuahuaAdorer please helpppp
I just need part c.
@ganeshie8 could you help please?
average rate of change of the graph from x = 2 to x = 5 is : \[\large \dfrac{f(5) - f(2)}{5-2}\]
look at the graph, whats the value of f(5) ? whats the value of f(2) ?
Im so confused.
@ganeshie8 is f(5) 160?
Correct ! what about f(2) ?
:D i was not expecting that to be right.
f(2) is 100 @ganeshie8
Excellent ! plug them in the average rate formula and simplify
\[\large \dfrac{f(5) - f(2)}{5-2}\] \[\large \dfrac{160-100}{5-2}\] simplify
omg thank you so much.
@ganeshie8
yw :) btw average rate of change represents how profit changes with increase in price of pencil
