First, let's reveal the definition of the derivative.
00:07
The derivative of function fx equals limit.
00:14
H goes to 0, fx plus h minus fx, over h.
00:26
And in this exercise, we want to find the value of the limit.
00:32
H goes to 0, 3, 2 plus h squared minus 2 plus h, minus 10 over h.
00:49
Note that if i assume fx equals 3x squared minus x, then f prime x equals limit, h goes, to 0, 3 times x plus h squared minus x plus h minus 3x squared minus x over h.
01:40
And if we evaluate the derivative at x equals to 2, it gives us 3 2 plus h squared minus 2 plus h...
