Answer:


(a)\ u \le -4


(b)\ u =\{-\infty,.....,-6,-5,-4\}

Explanation:

Given


-u \ge 4

Solving (a): An equivalent inequality

We have:


-u \ge 4

Multiply both sides by -1 (this changes the inequality)


-u*-1 \le 4 * -1


u \le -4

Solving (b): Values of u from least to greatest


u \le -4 implies that u ends at -4, starting from negative infinity

So, the list is:


u =\{-\infty,.....,-6,-5,-4\}
