Your prediction on the previous page was way too lowtoo lowabout righttoo highway too high.
The data show that the population of lily pads has a steady ✔ an increasing a decreasing growth rate.
A logarithmic✔ An exponentialA linearA quadratic function would be most suitable to model these data.
The general form of an exponential function is y = abx. Use the regression calculator to find the values of a and b for the water lily population growth. Round to the nearest thousandth.
Type the data that you collected (shown right) into the regression calculator. Be sure to choose a good window setting! The general form of an exponential function is y = abx. Use the regression calculator to find the values of a and b for the water lily population growth. Round to the nearest thousandth.
The graph to the right shows what you should have gotten on the regression calculator. Check all statements below that accurately describe the regression equation.
In terms of the water lily population change, the value 3.915 represents:
The value 3.915 represents the initial number of water lilies (the y-intercept), which is approximately 4. The value 1.106 represents the growth factor, indicating that the population grows by about 10.6% each day.
Which two equations below could you solve to find D, the number of days it takes the water lily population to double?
