Answer:
No, the two sets are not disjoint.
Step-by-step explanation:
Set of triangular numbers to 50: 1, 3, 6, 10, 15, 21, 28, 36, 45
Set of square numbers to 50: 1, 4, 9, 16, 25, 36, 49
They have 1 and 36 in common, so they are not disjoint, or in other words, they have some of the same numbers.
Third option: and
Given:
For a modulus function, if , then,
Here, ,
∴
Therefore, the third option is the correct answer as the graph has values as -2 and 2
here's the answer to your question
the answer is B
