find inverse of the function x^5-3over 2

Solution

To find the inverse of the function f(x)=x532f(x) = \frac{x^5 - 3}{2}, let's go step by step:

  1. Start with the given function:

    y=x532y = \frac{x^5 - 3}{2}

  2. Swap xx and yy to begin the process of finding the inverse:

    x=y532x = \frac{y^5 - 3}{2}

  3. Solve for yy (which will be the inverse function):

    • Multiply both sides by 2 to get rid of the denominator: 2x=y532x = y^5 - 3

    • Add 3 to both sides: 2x+3=y52x + 3 = y^5

    • Take the fifth root of both sides: y=2x+35y = \sqrt[5]{2x + 3}

  4. Thus, the inverse function is:

    f1(x)=2x+35f^{-1}(x) = \sqrt[5]{2x + 3}
