Consider the following function. f(x) = 9 − x2/3 Find f(−27) and f(27). f(−27) = f(27) = Find all values c in (−27, 27) such tha
oksano4ka [1.4K]

I guess the function is f(x)=9-x^{2/3}. Then f(-27)=0 and f(27)=0.

The derivative is f'(x)=-\dfrac23 x^{-1/3}, but there is no c such that

-\dfrac23c^{-1/3}=0

This doesn't contradict Rolle's theorem because f'(0) does not exists. In other words, f is not differentiable on (-27, 27), so the conditions of Rolle's theorem are not met. (Looks like that would be the last option, or the second to last option if the last one is "Nothing can be concluded")

How do you do this question?
Bess [88]

"T<u>he function is decreasing":</u>

This means the slope of the function will be negative at the given point.  Anywhere the line is going down, from left to right, is decreasing.  This eliminates choices A and C.

<u>"The function is concave down":</u>

This means the curve of the function will be open down (think of an upside down u).  This eliminates choice E.

<u>"f(x)>0":</u>

This is anywhere the curve is above the x axis.  This eliminates choice D.

The answer is Choice B) x=2.

Hope this helps!!
