Which table represents a relation that is not function?

Please

  1

Explanation:

Any relation with a repeated input value is not a function.

Table 1 has the input value 2 listed twice, so does not represent a function.

they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
