1. analyze dean's and emo's book collection effons.
a. virte a linear function to represent how many books dean and the pizzerie wil donate to commune
outreach programs. then describe the function in terms of increasing ordereasing and continuous
or discrete
b. write a linear function to represent how many books emio and the shoe store wil donate to sunrise
elementary school then describe the function in terms of increasing or decreasing and whether
is continuous or discrete.
