The common ratio is 2/5. Each number is 60% less in magnitude than the previous one.

Step-by-step explanation:

The numbers don't actually decrease; they increase. Each number is 2/5 of the previous one, so has "decreased" by 3/5 of its value, or 60%.

Find the derivative of the function by using the Product Rule. Simplify your answer. f(x) = (x - 3)(x + 3)

Morgarella [4.7K]

Answer:

$f'(x)=2x$

Step-by-step explanation:

Given : Function $f(x)=(x-3)(x+3)$

To find : The derivative of the function by using the Product Rule ?

Solution :

The product rule of derivative is

$\frac{d}{dx}(u\cdot v)=uv'+vu'$

Here, u=x-3 and v=x+3

$\frac{d}{dx}((x-3)\cdot (x+3))=(x-3)\frac{d}{dx}(x+3)+(x+3)\frac{d}{dx}(x-3)$

$\frac{d}{dx}((x-3)\cdot (x+3))=(x-3)1+(x+3)1$

$\frac{d}{dx}((x-3)\cdot (x+3))=x-3+x+3$

$\frac{d}{dx}((x-3)\cdot (x+3))=2x$

Therefore, $f'(x)=2x$
