Answer:
The inverse of f(x) is 
Step-by-step explanation:
To find the inverse of the function 
, perform the following steps:
1) do 
2) Solve the equation for the variable x.
3) exchange the variable x with the variable y
----> 
4) Change the variable y by 
Finally the inverse function is:
Start off by combining like terms on the LHS (the terms with x in them).
So we get
Replacing this result with what we had before on the LHS, we get
⇒Solve for x (divide both sides
)
⇒Don't forget about reciprocity rules when dividing. This is the same as multiplying both sides by
⇒
⇒
***This is a proper fraction
Every point on the line 3/7x -1 is a solution
Unless there is another line provided...
