Question

Which relation below represents a one to one function

Answer 1

Answer:

No table shows one-to-one function

One-to-one function is a function that preserves distinctness: it never maps distinct elements of its domain to the same element of its codomain. Every element of the function's domain is the image of at most one element of its domain.

First table:

No. Because for x = 12 and x = 14 we have the same value of y = 197

Second table:

Third table:

No. Because for x = 7.25 and x = 8.5 we have the same value of y = 11
