Find the inverse function

Find the inverse function for f(x) = 6x.

Solution

To find the inverse of the given function f(x)=6xf(x) = 6x, follow these steps:

  1. Start with the equation: y=6xy = 6x

  2. Swap xx and yy to find the inverse: x=6yx = 6y

  3. Solve for yy: y=x6y = \frac{x}{6}

  4. Express the inverse function: f1(x)=x6f^{-1}(x) = \frac{x}{6}

Final Answer:

The inverse function is: f1(x)=x6f^{-1}(x) = \frac{x}{6}
