Given f ( x ) = 3x - 2 determine f -1 ( x ) .
Solution
Now, already we know what the inverse to this function is as already we've done some work with it. Though, it would be nice to in fact start with this as we know what we have to get. This will work as a nice verification of the procedure.
Hence, let's get started. We'll replace first f ( x ) with y.
y = 3x - 2
Next, replace all of the x's along with y and all y's with x.
x = 3 y - 2
Now, solve out for y.
x + 2 = 3 y
1/3 ( x + 2) = y
Lastly replace y with f -1 ( x ) .
f -1 (x)= x/3 + 2/3
Now, we have to verify the results. Already we took care of this in the previous section, though; really we have to follow the procedure so we'll do that here. It doesn't matter which one from two that we verify we just have to check one of them. This time we'll check that ( f o f -1 )( x ) = x is true.
( f o f -1 )( x ) = f [ f -1 ( x )]
=f [ x/3 + 2/3 ]
= 3 ( x /3+ 2 /3) - 2
= x +2 - 2
= x
