In this problem we'll find use the method of Lagrange multipliers to find maximum and minimum values of the function f(x,y) = -2x +y+20 subject to the constraint r² + y? = 20. Here are several different views of the surface z = -2r + y + 20. The constraint r? + y = 20 is shown %3D drawn on the surface.

7. In this problem we'll find use the method of Lagrange multipliers to find maximum and minimum values
of the function
f(x, y) = -2x + y + 20
subject to the constraint r2 + y? = 20.
Here are several different views of the surface z = -2 + y+ 20. The constraint r? + y? = 20 is shown
drawn on the surface.
(a) Solve the system of equations Vƒ = \Vg, z² + y? = 20 to find the r and y coordinates of the
points shown where f attains maximum and minimum values.
