f inverse y=31x3f\text{ inverse }y=3\sqrt{1-x^3}

Solution

To find the inverse of the function y=31x3y = 3\sqrt{1 - x^3}, we need to express xx in terms of yy. Let's go through the steps to find the inverse function.

  1. Start with the given equation: y=31x3y = 3\sqrt{1 - x^3}

  2. Isolate the square root term: y3=1x3\frac{y}{3} = \sqrt{1 - x^3}

  3. Square both sides to eliminate the square root: (y3)2=1x3\left(\frac{y}{3}\right)^2 = 1 - x^3

  4. Simplify: y29=1x3\frac{y^2}{9} = 1 - x^3

  5. Isolate x3x^3: x3=1y29x^3 = 1 - \frac{y^2}{9}

  6. Solve for xx: x=1y293x = \sqrt[3]{1 - \frac{y^2}{9}}

Thus, the inverse function is: f1(y)=1y293f^{-1}(y) = \sqrt[3]{1 - \frac{y^2}{9}}
