Need Help With Finding The Gradient Of A Function

[From: ] [author: ] [Date: 11-08-10] [Hit: ]
Hope that helps!-f (x) = 2 - 10xyou can find the gradient of this function in every point by putting x in the f (x).......
If f(x)=2x-5x^2 Find f '(x)

Thanks show working.

Well then you know that this equation is 2x^1-5x^2 right?
So then you multiply the power to the number in front of x and minus one to the power,
Therefore, 2*1x^(1-1)-5*2x^(2-1)
Which equals 2-10x as x^(0) is 1.
Hope that helps!

f '(x) = 2 - 10x
you can find the gradient of this function in every point by putting x in the f '(x).
