Find all the local maxima, local minima, and saddle points of the function.
A. f(0, 0) = 641, local maximum; f(2, 5) = 0, local minimum; f(2, -5) = 0, local minimum;
local minimum; f(-2, -5) = 0, local minimum
B. f(0, 0) = 641, local maximum; f(-2, -5) = 0, local minimum
C. f(0, 0) = 641, local maximum; f(0, 5) = 16, saddle point; f(2, 0) = 625, saddle point;
f(2, 5) = 0, local minimum; f(-2, -5) = 0, local minimum
D. f(0, 0) = 641, local maximum; f(0, 5) = 16, saddle point; f(0, -5) = 16, saddle point;
f(2, 0) = 641, saddle point; f(2, 5) = 0, local minimum; f(2, -5) = 0, local minimum;
f(-2, 0) = 625, saddle point; f(-2, 5) = 0, local minimum; f(-2, -5) = 0, local minimum
This follows as a Corollary to the Parallel Postulate:
