## anonymous one year ago What's the derivative of (-1/x^2-4)? Using chain rule

1. yolomcswagginsggg

−4x2−1 x2

2. Vocaloid

start by rewriting the function with a negative exponent

3. yolomcswagginsggg

−4x2−1/x2

4. Vocaloid

(-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)

5. Vocaloid

small typo

6. Vocaloid

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

7. IrishBoy123

is it $f(x) = {-1 \over x^2-4}$ ??? or maybe $f(x) = { -1 \over x^2}-4$ ??
