Part 1
The function
f left parenthesis x right parenthesis equals x cubed minus 6f(x)=x3−6
is one-to-one.
Find an equation for
f Superscript negative 1 Baseline left parenthesis x right parenthesisf−1(x),
the inverse function.
Solution
To find the inverse of the function , we need to follow these steps:
Step 1: Replace with
Let , so:
Step 2: Swap and
To find the inverse, swap and :
Step 3: Solve for
Now solve for in terms of :
Step 4: Write the inverse function
So the inverse function is:
