After the age of about 25 years, the average size of the pupils in a person’s eyes decreases. An approximate model for the average pupil diameter d (in millimeters) under low-light conditions as a function of age a (in years) is

At about what age does the average diameter fall below 6 millimeters?

A small bookstore starts a customer loyalty program. Over the first year, the total number of customers who have signed up can be modeled by the function shown in the photo, where c is the number of customers and w is how many weeks the program has been in effect.
