Question

Do the set of points in the figure represents a function? Yes No

Answer 1

Answer:

Yes

Step-by-step explanation:

We are given a set of points in the graph.

The coordinates are  (1, 2), (2, 1), (3, 0), (-1, 4)

The coordinates are in the form (x, y), where "x" represents the domain and "y" represents the range.

We can see that the each x value associate with unique value of y or only one element of y.

By definition of function, If each input is associated with only one output, then the relation is called function.

Therefore, the given set of points in the figure represents a function.

Note: We can also use vertical line test. If we connect the points, then we will get a line. When we draw a vertical line, the line touches the line at only one point. If the vertical line touches the graph at only one point, then it is a function.

Therefore, the answer is Yes

Answer 2

Answer:

yes because if you put a vertical line on it it only goes threw it once it is also called the vertical line test.
