1. From 2010-2020 the median home value in the city of Fort William grew exponentially. The median home value during this time period changed by 12% per year.
If the 1-year percent change is 12%, what is the 1-year growth factor?
Use your answer to part (a) to complete the following table of values showing the median home value in Fort William at various times.
| years since the beginning of 2010, tt | median home value in Fort William (in dollars) |
| 0 | 182,400 |
| 1 | 204,288 |
| 2 | |
| 3.25 | 263,623 |
| 4.25 | |
| 5.25 |
Define a function ff that models the median home value in Fort William tt years since the beginning of 2010 (assuming 0≤t≤10). Be sure to use function notation.
2. A city's population grows exponentially by 5% per year.
What is the 1-year growth factor for the population?
Fill in the missing information in the table below.
| years since the beginning of 2015, n | the city's population, p=g(n) |
| 0 | 160,000 |
| 1 | 168,000 |
| 2 | 176400 |
| 4.25 | 196,800 |
| 5.25 | 206711 |
c. Define a function g to model the citys population n years since the beginning of 2015.
3. The given table of values represents an exponential function (that is, a relationship where the growth factor is constant for the same size changes in x).
| x | y=f(x) |
| -1 | 384 |
| 0 | 576 |
| 1 | 864 |
| 2 | 1,296 |
Use the entries in the table to determine the 1-unit growth factor for y in this relationship.
The 1-unit growth factor is .
The 1-unit percent change for values of y is %
Define a formula for function f. Be sure to use function notation.
Fill in the missing entries in the table. Note: Pay close attention to how the values of x change. Not all changes are 1 unit. You can also use the formula you defined.
| x | y=f(x) |
| -1 | 384 |
| 0 | 576 |
| 1 | 864 |
| 2 | 1,296 |
