Answer:
25%
Step-by-step explanation:
50 is 1/4 of 200 and 1/4 of 100% is 25%
The inverse of the function is 
Explanation:
The given function is 
To determine the inverse of a function, we need to interchange the variables and solve for y.
Let us interchange the variables x and y
Thus, we have,

Now, we shall solve for y
Subtracting both sides of the equation by 4, we get,

Multiplying both sides of the equation by
, we get,

Switch sides, we have,

Multiplying the terms within the bracket, we have,

Thus, the inverse of the function is
