For the function f(x)
WITCHER [35]

Given:

The function is

f(x)=\dfrac{8\sqrt[3]{x}-8}{9}

To find:

The inverse function f^{-1}(x).

Solution:

We have,

f(x)=\dfrac{8\sqrt[3]{x}-8}{9}

Step 1: Putting f(x)=y, we get

y=\dfrac{8\sqrt[3]{x}-8}{9}

Step 2: Interchange x and y.

x=\dfrac{8\sqrt[3]{y}-8}{9}

Step 3: Isolate variable y.

9x=8\sqrt[3]{y}-8

9x+8=8\sqrt[3]{y}

\dfrac{9x+8}{8}=\sqrt[3]{y}

Taking cube on both sides, we get

\left(\dfrac{9x+8}{8}\right)^3=y

y=\left(\dfrac{9x+8}{8}\right)^3

Step 4: Putting y=f^{-1}(x), we get

f^{-1}(x)=\left(\dfrac{9x+8}{8}\right)^3

Therefore, the correct option is C.

Answer:

<u>Given data:</u>

  • 4, 5, 3, 3, 1, 2, 3, 2, 4, 8, 2, 4, 4, 5, 2, 3, 6,2

<u>Put the data in the ascending order:</u>

  • 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 6, 8

<u>Mean, the average:</u>

  • (1 + 2*5 + 3*4 + 4*4 + 5*2 + 6 + 8)/18 = 3.5

<u>Median, average of middle two numbers:</u>

  • 3

<u>Mode, the most repeated number:</u>

  • 2 (repeated 5 times)

Mean is normally the best measure of central tendency, same applies to this data.

#19 how do you do the work???!
Semenov [28]

Answer:

x=\frac{1}{3}

Step-by-step explanation:

move the terms with x to the left side of the equation:

add 3x to both sides

3x-1+3x=1

add 3x and 3x

6x-1=1

move all term not containing x to the right side:

add 1 to both sides of the equation

6x=1+1

6x=2

divide each term by 6

\frac{6x}{6}=\frac{2}{6}

x=\frac{2}{6}

simplify the fraction

x=\frac{1}{3}
