The graph of a function is shown below, which of the following correctly identifies the set of outputs?

The set of outputs are an ordered list of y-values. The question will ask for all y-values given by the ordered pairs on the graph.
Identify the ordered pairs:
(-5, 4), (-2, -1), (-1, 3), (4, -3)
Take all of the y-values, and put them into a set:
{4, -1, 3, -3}
Order the values from least to greatest:
{-3, -1, 3, 4}
The set that correctly identifies the set of outputs will be the first answer, {-3, -1, 3, 4}.
Remember that the "outputs" of a function are represented as y-values in functions. Thus, in this case we are trying to find the set of y-values the function produces.
According to the graph, that set would be {-3, -1, 3, 4}, or Choice A.
