Your immaturity* has been excused. Now if you don't mind, discuss your boredom in chat as I would like to solve this.

Have you googled. Google helps me in these situations

this 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?

i presume this is precalculus ?

Yes, 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.

I 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)

It's possible my answer was incorrect because I added instead of subtracted, one moment please.

do you know how to differentiate ?

OmidVBest ResponseYou've already chosen the best response.0
I 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)

Yeah that's definitely it, I'm not sure how I managed to mess that up during the test.

to find the slope is simply the rise/run

Nice, solved my own question :D does that mean I get a medal for good answer? ;)

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

f(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

Thanks saso, I got the answer now :D

ok some part of it got missing... \[\huge \frac{f(2+h)f(2)}{h} \]

yw :) i hope it's clear though

OmidVBest ResponseYou've already chosen the best response.0
Yup, 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
