Thread: Relative Max and Relative Min

f(x) = (x-2)^3 / x^2

find the relative max and min.

so obviously i would bring the x^2 up.

this is what i have so far,

<sup>= <sub>x^2(x-2)^3-(x-2)^3(x^2)

=x^2(3)(x-2)^2-(x-2)^3(2)(x)</sub></sup>



​is this correct so far?

If you wish to use the product rule rather than the quotient rule by bringing the denominator up as a factor, then you need to negate its exponent.

let me re-write this.

x^2(x-2)^3 - (x-2)^3-(x^2) / x^4

and the next step, i believe is the derivative right? but i am a bit confused with (x-2)^3. is the derivative of this 3(x-2)^2 or is it just 3x^2?

We are given the function:



Using the quotient rule, we find:
