Answer:
Step-by-step explanation:
First, notice that:
We proceed to use the chain rule to find using the fact that to find their derivatives:
Because we know then:
We substitute in what we had:
Now we put in the values in the formula:
Because of what we supposed:
And we operate to discover that:
and this will be our answer
Answer:
x=5
Step-by-step explanation:
I was working on this problem also.
Maybe my version will help, too.
You need to sketch f given the information you have.
f'(x) is approximately a a cubic polynomial which means f will look like a quartic (think W)
f slopes down (negative slope) to x=2 and then slopes down again...this is a horizontal tangent.
f then slopes down to to x=5 where is has a minimum and then slopes up.
if im not wrong
ALL of their points are common. If you multiply each side of the first equation by 2, you'll see that they're both the same line.
