Question

The big-omega notation for f(x, y) = x^5y^3 + x^4y^4 + x^3y^5 is?

(a) x^5y^3

(b) x^5y^5

(c) x^3y^3

(d) x^4y^4

I got this question in quiz.

My doubt stems from The Growth of Functions in section Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics

Answer 1

Correct option is (c) x^3y^3

To elaborate: x^5y^3,  x^4y^4 and x^3y^5 is greater than or equal to x^3y^3.
