**Objective:** Determine the global extreme values of the function on the given set without using calculus.

**Function:**
\[ f(x, y) = 6e^{-(5x^2 + 9y^2)} \]

**Constraint/Set:**
\[ 5x^2 + 9y^2 \leq 2 \]

**Tasks:**
- Find \( f_{\text{min}} = \)
- Find \( f_{\text{max}} = \)

**Notes:**
- The function \( f(x, y) = 6e^{-(5x^2 + 9y^2)} \) is an exponential function with a Gaussian distribution-like shape, where the argument of the exponent, \(-(5x^2 + 9y^2)\), determines its spread and direction. 
- The constraint \( 5x^2 + 9y^2 \leq 2 \) describes an ellipse in the xy-plane. 

The task is to determine the extreme values by considering the behavior of the function under the constraint of the elliptical form without using traditional calculus methods such as differentiation.
