Question

Which of the following best describes the graph above?

A. Function only
B. Relation only
C. Both relation and function
D. Neither relation nor a function

Answer 1

Answer: C

Explanation:

We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.

So, basically, if a graph is a function, it is a relation as well.

Let’s check if this is a function.

We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function

In our case, it passes the vertical line test.

Therefore, it is both a function and a relation, which corresponds to letter C.

Hope this helps! :)
