Answer:

See Explanation

Step-by-step explanation:

Your question is incomplete. I will take the complete question as:

f(x) = -x^2

Interval: [-1,1]

Required

Determine whether Rollie's theorem can be applied or not

First, find the coordinates of the endpoints on the closed interval [-1, 1]

f(x) = -x^2

f(-1) = -(-1)^2 = -1 ------ (-1,-1)

f(1) = -(1)^2 =-1 ---- (1,-1)

Find the derivative of f(x)

f(x) = -x^2

f'(x) = -2x

Calculate the slope (m) of the secant line i.e. (-1,-1) and (1,-1)

m = \frac{-1 - (-1)}{1 - (-1)}

m = \frac{-1 +1}{1 +1}

m = \frac{0}{2}

m=0

Set the derivative to the calculated slope:

f'(x) = m

-2x = 0

x=0

Plug in 0 for x in f'(0)

f'(x) = -2x

f'(0) = -2 * 0

f'(0) = 0

<em>Since f'(0) is differentiable at x = 0. We can conclude that Rollie's theorem can be applied</em>
