Question

As part of an Earth Science project, Erin tracked the amount of rain fall for 4 weeks. She started tracking after finding some initial data on the year's rainfall to date: Week Rainfall 1 5.5 2 8 3 10.5 4 13 If the linear function representing the amount of rainfall each week is f(w) = 2.5w + 3, what does the 3 represent in this function?

Answer 1

The 3 that represent in this function is the "A. The amount of rainfall in week 0." zero weeks have passed, and there's already up to the 3 mark. if additional rain comes into the bin, the existing water is still thereso we add +3 every time
