Math Problem Statement

what is the invers of f(x+3) = x+5/x-2 ,x=/2

only give me the answers and how to get it, and make sure that it's right

Solution

To find the inverse of the function f(x+3)=x+5x2f(x+3) = \frac{x+5}{x-2}, follow these steps:

Step 1: Replace f(x+3)f(x+3) with yy

y=x+5x2y = \frac{x+5}{x-2}

Step 2: Solve for xx in terms of yy

Multiply both sides by (x2)(x-2) to get rid of the denominator: y(x2)=x+5y(x - 2) = x + 5 Expand the left-hand side: [ yx - 2y = x +
