Suppose the data below are the result of a study of a medication used to fight a certain bacteria. The x column represents the number of hours after the medication was introduced to the bacteria and the y column represents the number of bacteria present. Use the data in the table below to answer each question.

1. What does the scatterplot of the data show?
   

AA strong positive linear relationship

BA strong negative linear relationship

CA curve that represents exponential growth

DA curve that represents exponential decay

1. Complete an exponential transformation on the y-values. What is the new value of y when x = 5?
   

A1.301

B0.699

C1.4472

D1.1761

1. Find the linear transformation model.
   

ALog y^ (y-hat) = -12.1667x + 84.8333

BLog y^ (y-hat) = 84.8333x – 12.167

CLog y^ (y-hat) = -0.1375x + 1.9978

DLog y^ (y-hat) = 1.9978x – 0.1375

1. Predict the number of bacteria present for 12 hours.
   

A0.35

B2.23

C-61
