Math Problem Statement
If f (x) = one-ninth x minus 2, what is mc003-2.jpg? mc003-3.jpg mc003-4.jpg f Superscript negative 1 Baseline (x) = one-ninth x + 2 f Superscript negative 1 Baseline (x) = negative 2 x + one-ninth
Solution
We are given the function:
We need to determine its inverse, .
Step 1: Replace with
Step 2: Swap and
Step 3: Solve for
-
Add 2 to both sides:
-
Multiply both sides by 9 to isolate :
-
Expand:
Step 4: Write the inverse function
