How do I differentiate this?​

&

Step-by-step explanation:

I'm sure you are familiar with the product rule,

If y = u*v => dy/dx = u * dv/dx + v * dy/dx <----- product rule

In this case:

Now remember the sum rule:

For this second bit we apply the chain rule:

If we substitute these values back into the expression...

...we get the following:

The rest is just pure simplification:

Now let's equate this to equal 8 for the second bit and solve for x:

what's that

constants mean the stopped points or the points on a graph that nothing is changing, hope this
