Question

A diver starts at the surface of the water and travels 8 feet to the bottom.

Graph A shows her distance from the bottom during the journey.

Graph B will show her distance from the surface during the journey.


Complete each statement about Graph B.

Answer 1

On Graph B, at 0 seconds, the graph will be at 0 feet.

Then the graph will increase until 2 seconds, when the diver reaches her deepest point. At 2 seconds the height of Graph B will be at 8 feet.

Explanation:

It just works.

Answer 2

On the graph B, at 0 seconds the graph will be at
`y=0.`

The graph will be going down until 2 seconds, when the diver reaches her deepest point. At 2 seconds the height of the graph will be -8ft.

Explanation:

In graph B we are measuring the distance from the surface, that is we are setting the surface to be y=0. Thus if the diver reaches her deepest point 8ft down, she will be below y=0 and at -8ft.

Thus, in shape the graph B will be similar to graph A, but it will be shifted downed by 8ft.
