Answer:

f^{-1}(x) = \sqrt[3]{x+5}

Step-by-step explanation:

A function f^{-1} is the inverse of f if whenever y =f(x) and x =f^{-1}

To find the  inverse of f(x) = x^{3} - 5, we use the following steps:

  • Step 1 : Put y for f(x) and solve for x

y = x^{3} - 5

<=> x^{3}  = y + 5

<=> x = \sqrt[3]{y+ 5}

  • Step 2: Put f^{-1}(y) for x, we have:

f^{-1}(y) =\sqrt[3]{y+5}

  • Step 3: Interchange y =x, we have

f^{-1}(x) = \sqrt[3]{x+5}

Let Calculate 3 points on f(x)

x = 0 => y = -5

x = 1  => y = -4

x = 2 => y = 3

Let Calculate 3 points on f^{-1} (x)

x = -5 => y = 0

x = -4  => y = 1

x = 3 => y = 2

Yes, the inverse is correct because:

  • the domain of the inverse function is the range of the original function
  • the range of the inverse function is the domain of the original function
