Find the corresponding values of f(x) for every value of x in the table, as shown below
Similarly, in the case of g(x),
The values above are the answers to part (a)
(b) Notice that,
[tex]\begin{gathered} 128>81\Rightarrow f(4)>g(4) \\ 250>243\Rightarrow f(5)>g(5) \\ 432<729\Rightarrow f(6)
Therefore, f(x) is sometimes less than g(x).
