Determine whether the function described below is increasing, decreasing, or constant:
Each number is multiplied by the same number with different signs.
The function is:
Let's start by assuming that equals 0:
Now let's assume that equals 1:
Now let's assume that equals -1:
Now let's assume that equals 2:
Now let's assume that equals -2:
Finally, let's plot all of the points on a graph:
We can see that the function both increases and decreases.
