Answer:

No

Step-by-step explanation:

Do a vertical line test.

First, put your pencil or ruler up against the screen.

Move it down the graph and if there are two points in one x point, it is not a function. For example, look at 0, 3 and 0, -2.5. They share the same x point.

Therefore, it is not a function.

Answer:

In the graph of a circle, we can easily draw a straight vertical line passing through its center. This will hit the top and the bottom of the shape. Since this line hits two points, a circle's graph is not a function. We can also observe the equation of a circle.

Answer:

A could represent the volume of a full bottle of the hot sauce.

Step-by-step explanation:

If we say that a full bottle of hot sauce is 100 ml, 90% of that would be 90ml, meaning that <em>x</em> is 90ml.

In this scenario, (10/9)x would equal 100ml, so it has to be the answer.
