The correct interpretation of the function \( ƒ(x) = 275(1.15)^x \) is:

**D. The number of bacteria increases at a rate of 15% each day.**

This is because the term \( (1.15)^x \) indicates that the population of bacteria grows by 15% for each additional day, starting from the initial amount of 275.
