Best ResponseYou've already chosen the best response.0:))) Part B and C are my struggles

Best ResponseYou've already chosen the best response.0Does that have an affect on the overall answer for part A because I figured that I just didn't find it relevant to state.

Best ResponseYou've already chosen the best response.0ok, it looks like your answer for A is mostly correct. Your domain for this function would be [0, 6] because those are the relevant x values. It looks like you used yvalues for each part. The function is increasing on (0, 3) and decreasing on (3,6).

Best ResponseYou've already chosen the best response.0C would be which tho cuz its rate of change isn't that time and speed or something?

Best ResponseYou've already chosen the best response.0^^That was a correction for A. For b, it's asking for the domain (xvalues) if the minimum of the function was $60. You want to look find the two points on the graph where y = 60, and use them to be the domain for B.

Best ResponseYou've already chosen the best response.0would it be then (60,1) AND (60,5) ?

Best ResponseYou've already chosen the best response.0x comes first, so (1, 60) and (5, 60). Which means the domain would be [1, 5]

Best ResponseYou've already chosen the best response.0For C, any function can have a rate of change. It just has different meanings for different applications. For this function rate of change is amount of profit gained or lost for each increases in price

Best ResponseYou've already chosen the best response.0Ok and also another question regarding A you wrote (0, 3) wouldn't that be (0,30) because the 3 isn't shown?

Best ResponseYou've already chosen the best response.0It's kind of hard to keep track of when you're starting out. Domains/ranges are represented by intervals, which uses the same notation as points. (0, 3) in part A is an interval, meaning the function is increasing from x = 0 to x = 3. It's not the point (0, 3).

Best ResponseYou've already chosen the best response.0does that make sense?

Best ResponseYou've already chosen the best response.0yes it does make sense when its not meaning a point :P

Best ResponseYou've already chosen the best response.0ok. for part C do you need help finding the rate of change?

anonymous

Best ResponseYou've already chosen the best response.0Yes i do cuz honestly I dont understand rate of change what so ever i figured its just the number but its a lot more confusing than it seems for me lol if that makes sense

Best ResponseYou've already chosen the best response.0let me ask you this, do you know how to find the slope given 2 points?

Best ResponseYou've already chosen the best response.0\[m=\frac{ y_2y_1 }{ x_2x_1 }\] look familiar?

Best ResponseYou've already chosen the best response.0isn't the slope y=mx+b

Best ResponseYou've already chosen the best response.0y= mx+b is the equation of a line. The slope is just m. Your problem has a parabola. But you can use the same formula to find rate of change. They want rate of change from 3 to 5. When x = 3, y = 120 When x = 5, y = 60 \[m=\frac{ 60120 }{ 53 }=\frac{ 60 }{ 2 }=30\]

Best ResponseYou've already chosen the best response.0so the rate of change is 30
