Find the inverse function of f(x) = x+2/x+1

(x) =

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject

y = ( multiply both sides by (x + 1)

y(x + 1) = x + 2 ← distribute left side

yx + y = x + 2 ( subtract x from both sides )

yx - x + y = 2 ( subtract y from both sides )

yx - x = 2 - y ← factor out x on the left side

x(y - 1) = 2 - y ← divide both sides by (y - 1 )

x =

Change y back into terms of x, thus

(x) =

Step-by-step explanation:

Inverse is when you swap the x's and y's and solve for y.  f(x) is y.
