Answer:
Option (2)
Step-by-step explanation:
Given function is,
9y - 6 = 3x
y = 
To find the inverse of the given function,
1). Substitute x in place of y and y in place of x.
x = 
2). Now we have to solve this equation for the value of y.
9x = 3y + 6
3y = 9x - 6
y = (3x - 2)
Therefore, inverse of the given function is y = (3x - 2)
Option (2) will be the answer.
