Answer:

Explanation:

To find the inverse function of f(x) = x/2, we need to interchange the roles of x and y and solve for y.

Step 1: Replace f(x) with y.

y = x/2

Step 2: Swap x and y.

x = y/2

Step 3: Solve for y.

Multiply both sides of the equation by 2 to isolate y.

2x = y

Step 4: Replace y with f^(-1)(x) to represent the inverse function.

f^(-1)(x) = 2x

Therefore, the inverse function of f(x) = x/2 is f^(-1)(x) = 2x.

To verify this, we can apply the inverse function to the original function. If we plug in f^(-1)(x) = 2x into f(x), we should get x as the result.

f(f^(-1)(x)) = f(2x) = (2x)/2 = x

As we can see, applying the inverse function to the original function yields the input x. This confirms that f^(-1)(x) = 2x is indeed the inverse function of f(x) = x/2.
