Answer:






Explanation:
The given function approximating the assets (in billions of dollars) for a financial firm is:

Given that x = 7 corresponds to the year 2007 then:
- x = 13 corresponds to the year 2013.
- x = 16 corresponds to the year 2016.
- x = 19 corresponds to the year 2019.

Part (a)
B. To find the assets in 2013, substitute 13 for x and evaluate to find A(x).

In 2013 the assets are about $615.2 billion.

Part (b)
A. To find the assets in 2016, substitute 16 for x and evaluate to find A(x).

In 2016 the assets are about $716.9 billion.

Part (c)
A. To find the assets in 2019, substitute 19 for x and evaluate to find A(x).

In 2019 the assets are about $835.4 billion.
