Finding Relative Extrema In Exercises 29 and 30, examine the function for extrema without using the derivative tests and use a computer algebra system to graph the surface and verify your answers. ( Hint: By observation, determine whether it is possible for z to be negative. When is z equal to 0?)

z = ( x 2 y 2 ) 2 x 2 + y 2

To determine

To calculate: The relative extrema for the function z=(x2y2)2(x2+y2) and to verify the result graphically.

Explanation of Solution

Given: z=(x2y2)2(x2+y2)

Calculation: The function is a rational function. The numerator is an expression raised to the power 2 which implies the numerator would always be non-negative. Similarly, denominator is the sum of two expressions of power 2 which implies the denominator would always be non-negative.

This is sufficient to conclude that z would always by non-negative.

Hence, there would be no relative maxima but the function would attain a minimum value of 0
