For a particular bronchodilator, k has been estimated to be in the range 0.047 to 0.107 per hour. Find an expression for the halflife in terms of k, and obtain a plot of the halflife versus k for the indicated range.

Read your textbook again, then your math book, tell us how you would solve it if you didn't have MatLab, and what you have tried in MatLab to get started.
