If 
is the inverse of 
, then by definition of inverse functions,
Given 
, the inverse, if its exists, satisfies the equation above. Evaluate 
at the inverse, we have
Solve for the inverse:
Given 
, we do the same thing as before to find its inverse.
1) x= -4/3 alternative forms ->x=-1 1/3, x=-1.3
2) 2:3
Answer:
1. j = 1
2. since the equation isnt true it has no solutions.
