1 ) 9 x + 18 > 9 x - 27
9 x - 9 x > - 27 - 18
0 * x > - 45
Always true
2 ) 6 x - 13 < 9 x - 12
6 x - 6 x < - 12 + 13
0 * x < 1
Always true
3 ) - 6 ( 2 x - 10 ) + 12 x ≤ 180
- 12 x + 60 + 12 x ≤ 180
0 * x ≤ 180 - 60
0 * x ≤ 120
Always true.

Given:
The function is
To find:
The inverse function .
Solution:
We have,
Step 1: Putting f(x)=y, we get
Step 2: Interchange x and y.
Step 3: Isolate variable y.
Taking cube on both sides, we get
Step 4: Putting , we get
Therefore, the correct option is C.
