Exponential and Logarithmic Functions

Step 1

The data in the following table shows the results of a zombie outbreak as time goes by. The number of zombies includes those that have been infected, as well as compensates for those that have been eliminated by the survivors.

Determine which function best models the data in the table, and then give your best approximation for what specific function would model this data, i.e. f(x) = what?

Based on the model you found, which is the best prediction of the number of zombies in 4 days (12 days since the outbreak began)?

A hotel trying to attract new business built a banquet hall 8 years ago. The following table shows the number of events hosted in the hotel's banquet hall each year since it was built.

Is this data best represented by an exponential regression model or a logarithmic regression model?Write the equation for the appropriate regression model to the best of your abilities.

Using your equation that you developed, predict the number of events on the 14thyear.
