Question

answer attempt 1 out of 2 \
ewline the graph does not represent a function because at least one input is mapped to multiple outputs . for example, the input $x = \square$ is mapped to the approximate outputs of $y = \square$ and $y = \square$ .

Explanation:

Step1: Apply Vertical Line Test

A graph represents a function if any vertical line intersects it at most once. This graph fails this test, as vertical lines cross both curves.

Step2: Pick an input x-value

Choose an x-value that lies under both curves, e.g., $x=-5$.

Step3: Find corresponding y-values

For $x=-5$, the upper curve has $y\approx4$, and the lower curve has $y\approx-4$.

Answer:

The graph does not represent a function because at least one input is mapped to multiple outputs. For example, the input $x = -5$ is mapped to the approximate outputs of $y = 4$ and $y = -4$.
