Step 1
Given f(x, y) = x^4 + 8y^2 - 32xy, we need to find the first-order partial derivatives with respect to x and y. ∂f/∂x = 4x^3 - 32y ∂f/∂y = 16y - 32x Show more…

Use the first derivative test to determine the location of each local extremum and the value of the function at that extremum. f(x) = 3xe^(-x) No local extrema Local minimum at x = 3 Local maximum at x = 1 Local minimum at x = 2
