Answer:
The range of the graph is:
-3 ≤ y ≤ 3
Hence, option (B) is correct.
Step-by-step explanation:
We know that the range of a function is the set of values of the dependent variable 'y' for which a function is defined.
From the given graph, it is clear that the graph goes down at y=-3 and then goes up to y=3 and then goes down again.
In fact, this indicates that the range of the graph lies between y=-3 to y=3
Therefore, the range of the graph is:
-3 ≤ y ≤ 3
Hence, option (B) is correct.
Answer:
No, no, yes, no
Step-by-step explanation:
The first one is not random. He is sampling only the earliest gym goers.
The second one is not random. He is sampling only from one zip code.
The third one is random. He is using a random number generator.
The fourth one is not random. He is sampling only volunteers.
