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
