Which statement about the graph is true?

It is a function with the domain (0≤x≤14) and the range (-1≤y≤7)

Step-by-step explanation:

First, we can check if the graph is a function. To do this, we can apply the vertical line test: if any vertical line can be drawn that intersects the function multiple times, the graph is not a function. No such line can be drawn, so the graph is a function

Next, the domain represents all possible x values on the graph. The x axis is the horizontal one, as labeled on the graph, and goes from 0 to 14, inclusive. Therefore, the domain is (0≤x≤14)

Finally, the range represents all possible y values. The graph ranges from y = -1 to y = 7, inclusive, on the vertical axis, so the range can be represented by the inequality (-1≤y≤7)

answer: .64
