Sales Function Analysis and Interpretation

The video tutorial explains how to track sales using a table and function notation. It covers how to determine sales for specific years, find the year corresponding to a given sales figure, and solve equations involving the sales function. The tutorial uses a table where the first column represents years since 2000 and the second column shows items sold in thousands. Through examples, it demonstrates how to interpret and use this data to answer questions about sales figures and years.

What does the variable T represent in the sales table?

• The total sales in thousands

• The number of items sold

• The sales function output

• The year since 2000

In the sales table, what does the second column represent?

• The sales function input

• The year since 2000

• The sales function equation

• The items sold in thousands

How many items were sold in the year 2003?

• 47,000

• 41,000

• 34,000

• 42,000

If 42,000 items were sold, what year does this correspond to?

• 2005

• 2003

• 2004

• 2001

What is the function value s(1) in the sales table?

• 34

• 42

• 41

• 47

If s(T) equals 41, what is the value of T?

• 4

• 6

• 3

• 5
