Increasing

Step-by-step explanation:

The x-axis is the "time", and

The y-axis is the "water level".

In the line shown, as we go right in the x-axis (time axis), we see that the value of y axis (water level) increases (rises). According to the definition, we can clearly say that this function is increasing.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
