Determine whether there is a relative maximum, a relative minimum, a saddle point, or insufficient information to determine the nature of the function (x, y)

Determine whether there is a relative maximum, a relative minimum, a saddle point, or insufficient information to determine the nature of the function ƒ(x, y) at the critical point (x₀, y₀).

ƒ_xx(X₀, Y₀) = -9, ƒ_yy(X₀, Y₀) = 6, ƒ_xy(X₀, Y₀) = 10
