To make sure we don't have negatives under the square root, we specify that [tex]x \ge 0[/tex] (x is greater than or equal to 0). We'll use this fact later on
--------------------------------------------
Start with the given inequality [tex]\sqrt{x} \le 7[/tex] and square both sides to get [tex]x \le 49[/tex]. Couple this with the fact that [tex]x \ge 0[/tex] means we have this compound inequality [tex]0 \le x \le 49[/tex]
What does this mean? It means that we can pick any value from 0 to 49 (including both endpoints) and it will be a solution to the inequality. This applies to the values 49, 48 and 44
