For this problem, we've been given the function g of x equals x plus 4 divided by x squared.
00:07
And we want to find the value of the derivative of g of x at the given point, which is 2 .3.
00:15
So first, we need to find the derivative of our g function.
00:19
Well, we have a fraction here, and we have two choices.
00:23
We could either use the quotient rule and take the derivative of this as a quotient, or we can rewrite this giving x a negative exponent.
00:34
And then we can use the power rule.
00:36
And i think that's a little bit simpler.
00:37
So let's use that.
00:38
Again, you are certainly able to use the quotient rule.
00:41
You'll end up with the same answer either way...
