# Find the indicated derivative. \\ y =\frac{ t^2 + 9}{(2t - 8)^6}

## Question:

Find the indicated derivative.

{eq}y =\frac{ t^2 + 9}{(2t - 8)^6} {/eq}

## Rules of Differentiation:

There are four rules of differentiation.

1. Power Rule (applies to power functions)

2. Product Rule (applies to product of functions)

3. Quotient Rule (applies to quotient of functions)

4. Chain Rule (applies to composite functions)

The power rule states: {eq}(x^n)' = nx^{n-1} {/eq}

The quotient rule states: {eq}\left( \dfrac f g \right)' = \dfrac{f'g - fg'}{g^2} {/eq}

The chain rule states:

{eq}\left( f(g(x) \right)' = f'(g(x)) \cdot g'(x) {/eq}

We will use these three rules to differentiate this function.

We use the quotient rule to differentiate:

{eq}y' = \dfrac{(t^2+9)'(2t-8)^6 - (t^2+9)((2t-8)^6)'}{((2t-8)^6)^2} {/eq}

Now,

{eq}(t^2+9)' =... Differentiation Strategy: Definition & Examples
