Answer 1

Answer:

Answer: False

Step-by-step explanation:

Relations vs Functions

For a given relation between two variables x and y to be a function, it must meet the following condition: every value of x must be related to one and only one value of y.

When the graph of a relation is given, we can easily tell the difference by using the vertical line test as follows:

Imagine a vertical line moving through the x-axis. If any line touches the graph of the relation at more than one point, then the relation is not a function.

If we place vertical lines through the x-axis, they would touch the function twice at some values of x.

Thus, the graph is not a function

Answer: False
