Question 979132
Hello, i am having trouble solving for a function while studying. the example given is:

"find the inverse of the function f(x)= 1/x+2
a. y=1/x+2
b.____=1/y+2
c.x(y+2)=1
d.____=1/x
e.y=1/x-2=f^-1(x)

thank you for your help so much 
<pre>It appears as though the steps to finding the inverse of the function is laid out
{{{f(x) = 1/(x + 2)}}}
a. {{{y = 1/(x + 2)}}} ---------- Substituting y for f(x)
b. {{{x = 1/(y + 2)}}} ---------- Interchanging x and y
c. x(y + 2) = 1 -------- Cross-multiplying in order to isolate y
d. {{{y + 2 = 1/x}}} 
   {{{y = 1/x - 2}}} ------------ Isolating y
e. {{{highlight_green(f^(- 1)(x) = 1/x - 2))}}} ---- Replacing y with {{{f^(-1)(x)}}}
