Math Problem Statement

5(x2)x-2) In inverse mode

Solution

To find the inverse of the function represented by y=5(x2)y = 5(x - 2), follow these steps:

  1. Start with the original equation: y=5(x2)y = 5(x - 2)

  2. Swap yy and xx:
    To find the inverse, replace yy with xx and xx with yy. x=5(y2)x = 5(y - 2)

  3. Solve for yy:
    Isolate yy on one side of the equation to get the inverse function. x5=y2\frac{x}{5} = y - 2 y=x5+2y = \frac{x}{5} + 2

So, the inverse function is: y=x5+2y = \frac{x}{5} + 2 Or more commonly written as: f1(x)=x5+2f^{-1}(x) = \frac{x}{5} + 2
