FAN AND MEDAL
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:
graph of quadratic function f of x having x intercepts at ordered pairs 0, 0 and 6, 0. The vertex is at 3, 120
Part A: What do the xintercepts 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: What is an approximate average rate of change of the graph from x = 3 to x = 5, and what does this rate represent?

Best ResponseYou've already chosen the best response.1the xintercept means y = 0 f(x) = 0 f(x) = profit maximum value = highest y value = highest profit

Best ResponseYou've already chosen the best response.0so xintercept means theres 0 profit?

Best ResponseYou've already chosen the best response.1vertex is at 3, 120 so when x = 3 y = 120 3 pens maximum profit $120

Best ResponseYou've already chosen the best response.1equation for the graph can be written as f(x) = a(x  3)^2 + 120 because the vertex is at (3,120) and a is a constant to be found

Best ResponseYou've already chosen the best response.0f(x)=(x0)(x6)=0 is the equation?

welshfella

Best ResponseYou've already chosen the best response.1the zeroes of the equation are x=0 and x = 6 so we can plug these into f(x) = a(x 3)^2 + 120 0 = (3)^2 a + 120

Best ResponseYou've already chosen the best response.0i don't need the zeroes though, i only need the equation itself and thats it
