Which equation demonstrates the additive identity property?
(7+4)+(7-4) - 14
(7+41+0 -7+4
(7+40(1) - 7+4)
(744)+(-7-4)-0

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

hello, never fear papaguy is here!

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
