Question

How do you find the derivative of the function `f(x)=-2x^-3+x^2-7`?

Answer 1

`6x^-4 + 2x`

Explanation:

using the 'power rule'

If f(x`) = ax^n`

then `f'(x) = nax^(n-1)`

this is then applied to each term in the function.

`f'(x) = (-3)(-2)x^-4 + 2.1 x+ 0`

( the derivative of a constant term is 0 )
