Find f^-1(x) for f(x) = 1/x^3
kow [346]

Answer: f^{-1}(x) = \frac{\sqrt[3]{x^{2}}}{x}

<u>Step-by-step explanation:</u>

y = \frac{1}{x^{3}}

Inverse is when you swap the x's and y's and then solve for "y":

x = \frac{1}{y^{3}}

y^{3} = \frac{1}{x}

y = \frac{1}{\sqrt[3]{x}}

y = \frac{1}{\sqrt[3]{x}}*(\frac{\sqrt[3]{x}}{\sqrt[3]{x}})^{2}

y = \frac{\sqrt[3]{x^{2}}}{x}

You are reaching the price of MP3 players.Yiu found an average price of $58.80. One MP3 player cost $56 and another cost $62. Fi
tino4ka555 [31]

The price of third MP3 Player is $58.4

Further explanation:

Given

Price of first MP3 player= p1= $56

Price of second MP3 Player = p2= $62

Price of third MP3 Player=?

Average = X = $58.80

The formula for average is:

X =\frac{Sum}{No.\ of\ items}

We have 3 items.

Putting the values

58.80=\frac{56+62+p_3}{3}\\58.80*3=118+p_3\\176.4=118+p_3\\p_3=176.4-118\\p_3=58.4\ dollars

The price of third MP3 Player is $58.4
