2. A nutritionist wants to collect data on how much caffeine the average American drinks per day. She has the following ideas fo
r how she could obtain a sample: a. Ask the first 20 adults who arrive at a grocery store after 10:00 a.m. about the average amount of caffeine they consume each day. b. Every 30 minutes, ask the first adult who comes into a coffee shop about the average amount of caffeine they consume each day.
With composition of functions (as with the order of operations) we perform what is inside of the parentheses first. So, g(3)=2(3)+2=8 and then f(8)=24.
