Respuesta :

using a graphing tool

graph the functions

see the attached figure to better understand the problem

Remember that

A function f is bounded below if there is some number b that is less than or equal to every number in the range of f.

therefore

in this problem

g(x)=x^2 and g(x)=x^3 are bounded below
