2. Is S a function? Explain your reasoning.
Answers
Answer:
HOPE THIS HELPS!!
Step-by-step explanation:
1. The domain and range of relation S are as follows:
Domain: The domain refers to the set of all input values in a relation. In this case, the domain of S is {3, 2, 1}, which corresponds to the first element of each ordered pair in the relation.
Range: The range refers to the set of all output values in a relation. In this case, the range of S is {4, 3, 2, 1}, which corresponds to the second element of each ordered pair in the relation.
2. No, relation S is not a function.
To be considered a function, each input value (or element in the domain) should have only one corresponding output value (or element in the range). However, in the given relation S, the input value 2 is associated with both the output values 3 and 1.
Since one input value is associated with multiple output values, S fails the definition of a function.

Explanation
The translation of the points X<Y and Z makes a right triangle with legs 3 units and 4 units.
The distance between the correspong is the hypotenuse of the triangle.
Using the Pythagoras theorem;
c² = a² + b²
Where a and b are the legs and c is the hypotenuse.
c² = 3² + 4²
= 9 + 16
= 25
c = √25
= 5 units
