**Question 14: Which table describes an exponential function?** **Table a:** | x | 1 | 2 | 3 | 4 | |---|---|---|----|----| | y | 8 | 16 | 24 | 32 | **Table b:** | x | 1 | 2 | 3 | 4 | |---|---|---|----|----| | y | 4 | 8 | 16 | 32 | **Table c:** | x | 1 | 2 | 3 | 4 | |---|---|---|----|----| | y | 1 | 4 | 9 | 16 | **Table d:** | x | 1 | 2 | 3 | 4 | |---|---|---|----|----| | y | 2 | 4 | 6 | 8 | **Explanation:** In mathematical terms, an exponential function is identified by an equation of the form \( y = a \cdot b^x \), where \( a \) is a constant, \( b \) is the base of the exponent (b > 0 and \( b \neq 1 \)), and \( x \) is the exponent. Among the tables provided, the table that follows an exponential pattern is Table b, where the ratio between successive y-values remains constant (multiplication by 2): 4 to 8, 8 to 16, 16 to 32.

6. The function w(y) = -0.01y? + 0.27y+8.6 can be used to esimate the number of self-employed workers in the United States, in millions, y years after 1980 (d) Find how many self-employed workers the model predicts will there be in 2010. (e) What year(s) does the model predict has the most number of self-employed workers? How many self employed workers will there be in that year. (f) Find what the model predicts for the number of self-employed workers in 2026. Is this a good model for the year 2026 and beyond? Explain
