Investment A is on the rise, experiencing an increase in value, while Investment B is steadily decreasing during the first three years.

Adrianna utilizes exponential functions to model the values of two investments, A and B, with distinct representations. For Investment A, she describes key features, including an initial value of $2000 and an average rate of change over the interval [0, 3] as -95.1. Meanwhile, Investment B is represented by a table with x (number of years) and g(x) (values) columns, showcasing decreasing values over the first three years.

The correct statement regarding the two investments during the first three years is:

D. Investment A is increasing in value, but investment B is decreasing in value.

Investment A, characterized by an initial value and a negative average rate of change, is decreasing. In contrast, Investment B, illustrated in the table, experiences a decline in values from 1800 to 1543 over the first three years.

In summary, Investment A is bucking the decreasing trend, showing an increase in value, while Investment B is consistently decreasing. This analysis aligns with the selected option D.

The question probable may be:
