Question

Which of the following best describes the graph shown below

Answer 1

Since the graph of a linear function is a straight line, so the first option is not correct.
The given graph is of a function because for a particular value of y, there is a fixed value of 'x'.
Also, since there are two different values of x having same value for y, so the function is not one-to-one. For example, If y = f(x) is the function, then f(1.5) = f(-1) = 3.
Therefore, the graph represents a function, but it is not one-to-one.
Thus, the correct option is (A) THE ANSWER Is A

Answer 2

Answer:

A

Step-by-step explanation:

In the graph shown, no two y values share an x value. If you were to pass a vertical line through it at any point, it would only intersect it once, which makes it a function.

Many x values in the graph share y values; if you were to pass a horizontal line through it, it would intersect it more than once at certain points, which makes it NOT one-to-one.

This means that the answer is A: This is the graph of a function, but it's not one-to-one.
