I'm running through some homework and have got the question
find the gradient of the following curve at the given point
f(x) = 1 / x^2 @ (2, 0.25)
so I looked at 1 / x^2
and I'm thinking
if x^-1 = 1 / x
will 1/x^2 = x^-2? Or -x^2 ?
Or am I just going off on one?
Thankyou for any help you can provide
