Answer 1

In order to determine which set of ordered pairs does not represent a function, we need to check if any input (the first element of the pair) is associated with more than one output (the second element of the pair).

Let's analyze the given set of pairs:

\[
\{(0, 20), (2, 70), (10, 45), (1, 30), (3, 70)\}
\]

- Each first element (0, 2, 10, 1, 3) is unique and is mapped to exactly one output:
- 0 maps to 20
- 2 maps to 70
- 10 maps to 45
- 1 maps to 30
- 3 maps to 70

Since there are no repeated first elements with different second elements, this set does represent a function.

If you have additional sets of ordered pairs to compare, please provide them, and I can help you determine which one does not show a function!
