Best ResponseYou've already chosen the best response.2Find the slope of the line with those given x values as the x pints and use the y=x^2 to find the y parts. (x, y=x^2) for the given [2,5] so x=2 and x=5.

Best ResponseYou've already chosen the best response.2Average rate of change is the slope of the line defined by the end points of the sample. So for this sample range: dw:1440119916280:dw

Best ResponseYou've already chosen the best response.2Well, how do you get the slope of any line?

Best ResponseYou've already chosen the best response.2Close.  (y1  y2)/(x1  x2) OR (y2  y1)/(x2  x1) Either will get the same answer.

Best ResponseYou've already chosen the best response.2Well, you are given the domain [2,5]. Domain are x values. So that is your x1 and x2. You are given y = x^2. So use your x values to find your respective y values.

Best ResponseYou've already chosen the best response.2is that 2x or x^2?

Best ResponseYou've already chosen the best response.2If it is 2x, then yes, it would be (5,10). But if it is x^2 (a parabola) then it would be (5, 25).

Best ResponseYou've already chosen the best response.2FYI: Instant change is the slope of the tangent line. So instant change is also a slope. Rates of changes can basically be seen as a slope one way or another. This can help people visualize them on a graph...
