Find the inverse of the function f (x) = 6x/
(x−5)

To find the inverse of the function \( f(x) = \frac{6x}{x - 5} \), follow these steps:

### Step 1: Replace \( f(x) \) with \( y \)
We start by rewriting the equation as:
\[
y = \frac{6x}{x - 5}
\]

### Step 2: Swap \( y \) and \( x \)
To find the inverse function, swap \( y \) and \( x \):
\[
x = \frac{6y}{y - 5}
\]

### Step 3: Solve for \( y \)
Now, solve this equation for \( y \). Start by multiplying both sides of the equation by \( y - 5 \) to eliminate the denominator:
\[
x(y - 5) = 6y
\]
Expand the left-hand side:
\[
xy - 5x = 6y
\]
Move all terms involving \( y \) to one side:
\[
xy - 6y = 5x
\]
Factor out \( y \) on the left-hand side:
\[
y(x - 6) = 5x
\]
Solve for \( y \):
\[
y = \frac{5x}{x - 6}
\]

### Step 4: Write the inverse function
The inverse function is:
\[
f^{-1}(x) = \frac{5x}{x - 6}
\]

### Final Answer:
\[
f^{-1}(x) = \frac{5x}{x - 6}
\]
