You are implementing on a computer a numerical algorithm to solve an equation of the form f$($x$)=0$

$.$

In order to check your algorithm you decide to test it with the function f$($x$)=$x$3$

$.$

Question $7$Select one:

a$.$

This is not a good choice for the function f$($x$)$

to test the programmed algorithm

b$.$

This is a valid choice for the function f$($x$)$
