For this problem, we have been given a function, f of x equals x squared divided by x squared plus four.
00:07
And we've been asked to find the value of the derivative at the point zero, zero.
00:13
Now, this function is a quotient.
00:15
So we're going to need to use the quotient rule to find the value of our derivative.
00:20
So let's do a quick review.
00:21
If i have a quotient, f of x over g of x, there's my numerator and denominator.
00:27
If i want to take the derivative of this, that is, i start with the denominator times the derivative of the numerator, minus the numerator times the derivative of the denominator, and that's going to be all over the denominator squared.
00:47
So that is our quotient rule...
