Question #686f7

Answer 1

Yes, this represents a function.
It can be written as `f(x) = -2`

Explanation:

Yes, this represents a function.

It can be written as `f(x) = -2`

However, as there is no `x` term, no matter what `x` value you choose, the answer for `y` will be `-2`

For EACH `x`-value there is only ONE `y`-value.
This is the definition of a function.

This is known as a 'many-to-one' function, because many `x`-values will have the same y-value.

Possible points of this function could be :

`(8, -2), (3,-2), (0, -2), (-5, -2), (-10, -2) .....`

If you draw this as a graph you will get a horizontal line passing through `y=-2` on the `y`-axis.

Any vertical line draw will intersect the graph at only 1 point.
