Question

six graphs are shown below. click on the tabs to see them. graph 1 graph 2 graph 3 graph 4 graph 5 graph 6 check the box corresponding to each graph that represents a function. graph 1 graph 2 graph 3 graph 4 graph 5 graph 6 none of the gra try one last time

Explanation:

Step1: Recall function definition

A function is a relation where each input (x - value) has exactly one output (y - value).

Step2: Apply vertical - line test concept

Check if any vertical line intersects graph at more than one point. If not, it's a function.

Answer:

To determine if a graph represents a function, we use the vertical - line test. If any vertical line intersects the graph at more than one point, the graph does not represent a function. Since we only have Graph 3 shown and no other graphs are visible for analysis, we can only assess Graph 3. Without seeing all six graphs, we cannot fully answer which ones are functions. But for Graph 3, we would apply the vertical - line test. If for every x - value there is exactly one y - value, it is a function.
