Question

Is this an increasing function or a decreasing function?

Increasing



Decreasing

Answer 1

Increasing

Explanation:

The x-axis is the "time", and

The y-axis is the "water level".

• As we go right in the x axis, the y axis increases. This is an example of increasing function.
• As we go right in the x axis, the y axis decreases. This is an example of decreasing function.

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.
