Answer:
Your answer is DDDDDDDDD
Step-by-step explanation:
405.58
hope this helps!
1 ≤ c ≤ 3
In order to meet the standard, the chlorine level (c) must be at least 1 part per million (equal to or greater than 1):
1 ≤ c
At the same time, the level also needs to be no greater than 3 parts per million (equal to or lesser than 3)
c ≤ 3
Combining both inequalities yields (in parts per million):
1 ≤ c ≤ 3.
The compound inequality above describes the acceptable range for chlorine levels.
{(2,4), (-1, 7), (3,0), (5,4)}
{(-6, 1), (0, 1), (2, 1), (3, 1)}
{(-3, -3), (-1, 6), (4, 5), (5, 4)}
For a relation to be a function, the same x-value can't have multiple y-values.
For this reason, this relation is not a function:
{(-4,0), (-4,8), (-1, 3), (2,9)}
And these are functions:
