Which represents a function?

  the table

Step-by-step explanation:

Any mapping (graph, table, diagram, or ordered pairs) in which the same x-value gives two or more y-values (range values) is NOT a function.

In the diagram, -2 gives two outputs; in the ordered pairs, 6 gives two outputs. Neither the diagram nor the set of ordered pairs represents a function.

The table has unique values in the x-column, so it is a function.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
