Homework Statement
Find the maximum value of f(x,y)=xy+1 on the triangular region: x ≥ 0, y ≥ 0, x+y ≤ 1
The Attempt at a Solution
Partial derivatives of f(x,y) with respect to both x and y are positive within the given bounds, so the maxima will be found on the boundary where y=1-x. g(x) = -x2+x+1 and max value is 1.25
