Answer:
Q = 25y - 3y³
Explanation:
To write the objective function in terms of y, we need to express x in terms of y using the constraint equation:
x + 3y² = 25
x = 25 - 3y²
Now we can substitute this expression for x in the objective function:
Q = xy = y(25 - 3y²)
Expanding this expression gives:
Q = 25y - 3y³
Therefore, the objective function in terms of y is Q = 25y - 3y³
