Is 27 the problem number or is that part of the equation?
If 27 is part of the equation, then
f(x) = -(1/4)x^2 + 2x +39. That is not anything like your equation.
If the 27 is a problem number, you should not have types it as part of the equation. Is the minus sign in front of f(x) real, or a hyphen?
We can only answer math questions that are clearly written.
It's just the number of the problem.
