Answer:
No table shows one-to-one function
Explanation:
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:
No. Because for x = -2 and x = 2 we have the same value of y = 5
Third table:
No. Because for x = 7.25 and x = 8.5 we have the same value of y = 11
