Let's examine what is happening using a different model: 5. Run logistic regression (as demonstrated in the lecture for section 4.7) on your completed data table (see right) to find a model for the total amount in the blood stream as a function of t in DAYS. Call this model A ( t ) . Store this model in Y 1 in your calculator and then write the milel below. 0. Use your derivative rules to find a model for the instantaneous rate of change of the amount in the blood stream as a function of time in hours, A ? ( t ) . Show vou work in the space below. 7. Use your model for A ? ( t ) and/or the nDeriv function to calculate how quickly the Crestor quantity is increasing: a. at time 1 day b. at 2 days ( t = 2 ) c. at 3 days ( t = 3 ) 8. Using your understanding about the logistic model, what will happen to the total amount in the bloodstream if this patient continues this routine long-term? Draw a reasonable sketch of A ( t ) to support your claim. Let's examine what is happening using a different model: 5.
