Question

What's the derivative of (-1/x^2-4)? Using chain rule

Answer 1

−4x2−1
x2

Answer 2

start by rewriting the function with a negative exponent

Answer 3

−4x2−1/x2

Answer 4

(-1)*(x^2-4)^(-1)

bring the exponent down, then take the derivative of what's inside

the derivative is (-1)*(x^2-4)^(-2)*(2x)

Answer 5

small typo

Answer 6

(-1)(-1)*(x^2-4)^(-2)*(2x)

= (2x)*(x^2-4)^(-2)

Answer 7

is it
\[f(x) = {-1 \over x^2-4}\] ???

or maybe \[f(x) = { -1 \over x^2}-4\] ??
