Question

a.) Which relation is NOT a function?
b.)Explain using the definition.
{Hint: A function is a relation that pairs each domain(x) value with EXACTLY ONE range(y) value.}
Relation A: (-5,1),(-4,1),(-3,1),(-1,5), (1,7)
Relation B: (-2,3), (0,1), (1, 2), (2-4), (0,-7)

Answer 1

Answer:

Relation A is not a function.

Step-by-step explanation:

By definition, a function must have a single unique y-value output for each x value. In Relation A the same y-value 1 appears for 3 different x-values.
