3-4 Use the level curves in the figure to predict the location of
the critical points of f and whether f has a saddle point or a
local maximum or minimum at each critical point. Explain your
reasoning. Then use the Second Derivatives Test to confirm your
predictions.

Formula Formula A function f(x) attains a local maximum at x=a , if there exists a neighborhood (a−δ,a+δ) of a such that, f(x)<f(a), ∀ x∈(a−δ,a+δ),x≠a f(x)−f(a)<0, ∀ x∈(a−δ,a+δ),x≠a In such case, f(a) attains a local maximum value f(x) at x=a .
