Best ResponseYou've already chosen the best response.0Your immaturity* has been excused. Now if you don't mind, discuss your boredom in chat as I would like to solve this.

Best ResponseYou've already chosen the best response.2this is in a calculus class... right? i know the gradient function to be the first derivative of a curve function... not sure how to find the "rise" though... i suppose that means the height?

Best ResponseYou've already chosen the best response.0i presume this is precalculus ?

Best ResponseYou've already chosen the best response.0Yes, the height is the rise. Well, this is my first calculus course in college for computer engineering  computing science. It assumes no previous knowledge of calculus. If that's what precalc means then yes.

Best ResponseYou've already chosen the best response.0I remember it had something to do with the y at 2 being f(2), and then the y at 2+h being f(2+h)

Best ResponseYou've already chosen the best response.0It's possible my answer was incorrect because I added instead of subtracted, one moment please.

Best ResponseYou've already chosen the best response.0do you know how to differentiate ?

Best ResponseYou've already chosen the best response.0I recognize the term so probably, I just can't really think of an example atm. It's very late. Here, this is what I think I'm supposed to do to find the rise: y2  y1, y2 = f(2+h), y1 = f(2). f(2+h) = 4(2+h)^2 + 5(2+h), f(2) = 4(2)^2 + 5(2)

Best ResponseYou've already chosen the best response.0Yeah that's definitely it, I'm not sure how I managed to mess that up during the test.

Best ResponseYou've already chosen the best response.0to find the slope is simply the rise/run

Best ResponseYou've already chosen the best response.0Nice, solved my own question :D does that mean I get a medal for good answer? ;)

Best ResponseYou've already chosen the best response.0Yeah the slope was the "easy" part just divide by h basically.

Best ResponseYou've already chosen the best response.2f(2+h) is the function of the rise... you'll notice that f(2+h) is the y value as the x value = 2+hdw:1330589766893:dw

Best ResponseYou've already chosen the best response.0Thanks saso, I got the answer now :D

Best ResponseYou've already chosen the best response.2ok some part of it got missing... \[\huge \frac{f(2+h)f(2)}{h} \]

Best ResponseYou've already chosen the best response.2yw :) i hope it's clear though

Best ResponseYou've already chosen the best response.0Yup, I figured it out after retrying the question, I guess before I went through the right steps but I had 4h^2 + 13h as opposed to the correct 4h^2 + 21h (for the rise), so it was a calculation error and I assumed I was doing the problem wrong so came here for help :D
