Final answer:
The inverse function of 1/2x is 2y or 2x.
Step-by-step explanation:
The inverse function of 1/2x can be found by swapping the x variable with the y variable and solving for y.
Let's start by replacing y with 1/2x:
y = 1/2x
To find the inverse function, we need to solve for x.
Start by multiplying both sides of the equation by 2:
2y = x
Thus, the inverse function of 1/2x is 2y or 2x.
