The quantity of detergent in a liter of groundwater near an industrial area is expected to increase by 0.05 grams per year.
-Exponential growth
-Exponential decay
-Linear
-None of the above

C. Linear

Step-by-step explanation:

The problem says that the quantity will increase each year, so we can definitely get rid of exponential decay because that indicates that the graph will decrease.

Now, the problem says the quantity increases 0.05 grams per year. It doesn't say anything about multiplication or how one year's quantity is k times the previous year's quantity. That means this must not be exponential at all, eliminating A.

Instead, this is actually linear because the common difference that you add each year is 0.05.

The answer is thus C.

-Linear

Step-by-step explanation:

Per year increase of 0.05 is a constant rate, which means the slope of the graph is a constant.

Hence, it's a linear function
