Answer:

Explanation:
Given equation:

To write a formula for g(u), we need to solve the equation for v.
Begin by swapping sides:

Subtract 1 from both sides of the equation:


Divide both sides of the equation by the highest common factor 2:


Divide both sides of the equation by 4 to isolate v:


Replace v with g(u):

Therefore, the formula for g(u) is:
