It’s actually choice 4) -0.04

Step-by-step explanation:

You can see that as the years increase (when getting older), the size of the pupil decreases. So with that information, you can already eliminate choice 1 and 2 because they both show the rate of change increasing (which is wrong) and choice 3 and 4 shows the rate of change decreasing (which is right). To solve and find the right number, you can take any two numbers, subtract them, and divide them by 10. They reason why you do this because to want to find the difference in 10 years, and you divide it by 10 because the question wants us to find it per year (1 year).

Steps:

You can take 4.3 and 4.7, subtract to get -0.4, and divide it by 10 to get -0.04

You can also take 3.1 and 3.5, subtract to get -0.4, and divide it by 10 to get -0.04

-0.04
