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")

The ordered pairs in the table represent a linear function.

Illusion [34]

Answer:

If x = 7 y = 20

Step-by-step explanation:

As the x goes up by 1 you see that the y goes up by 2.

y = 2x + 6

Using that equation gets you your y

y = 2(7) + 6

y = 14 + 6

y = 20

The price of a ring was decreased by 25% to £390. <br> What was the price before the decrease

Over [174]

You will pay $292.5 for a item with original price of $390 when discounted 25%. In this example, if you buy an item at $390 with 25% discount, you will pay 390 - 97.5 = 292.5 dollars

What is the slope of this line? <br> The coordinates are: (-4,5),(0,6), and (8,8).

Elodia [21]

Answer:

Step-by-step explanation:

we have to use the formula of slope here.

we know,

slope of the line passing through (x1,y1) and (x2,y2) is-

$\frac{y2-y1}{x2-x1}$
