Question

Find the derivative of f(x) = -6/x at x = 12.

Answer 1

\(f(12)=\large \frac{6}{x^2}\)

Answer 2

You need to learn your derivative rules.

Answer 3

I know them, but I'm using them with limits. how you solve them is different @abb0t

Answer 4

It's just tedious algebra.

Answer 5

then let me ask, How did you get the x^2?

Answer 6
