Select the correct answer.

Let [tex]f(t)[/tex] be the number of units produced by a company [tex]t[/tex] years after opening in 2005. What is the correct interpretation of [tex]f(6) = 44,500[/tex]?

A. In 2006, 44,500 units are produced.
B. In 2011, 44,500 units are produced.
C. In 2009, 44,500 units are produced.
D. Six years from now, 44,500 units will be produced.

Answer :

To solve this problem, we need to interpret the meaning of [tex]\( f(6) = 44,500 \)[/tex] for the function [tex]\( f(t) \)[/tex], which represents the number of units produced by the company [tex]\( t \)[/tex] years after opening in 2005.

Let's analyze this step-by-step:

1. Understanding the Function: The function [tex]\( f(t) \)[/tex] tells us the number of units produced [tex]\( t \)[/tex] years after the company started in 2005.

2. Finding the Year: The expression [tex]\( f(6) = 44,500 \)[/tex] tells us that the function [tex]\( f \)[/tex] evaluates to 44,500 when [tex]\( t = 6 \)[/tex]. This means 6 years after the company started, 44,500 units were produced.

3. Calculating the Year: Since the company started in 2005, we add the 6 years to 2005 to find the specific year when 44,500 units were produced:
[tex]\[
2005 + 6 = 2011
\][/tex]

4. Conclusion: Therefore, in the year 2011, the company produced 44,500 units.

The correct interpretation of [tex]\( f(6) = 44,500 \)[/tex] is that in 2011, 44,500 units were produced. This matches with the answer option: "In 2011, 44,500 units are produced."
