Question 175983This question is from textbook Elementary Mathematical Modeling Functions and Graphs
: I'm given a scenario describing that for the first ounce in First Class Mail the rate is $0.37 and each additional ounce after that has a rate of $0.23 per ounce. Part (d) is asking me to write a multipart rule for the First-Class Mail rate function R(w), giving the rate in dollars and cents as a function of the weight in ounces.
and (e) what are the domain and range of the function R? This question is from textbook Elementary Mathematical Modeling Functions and Graphs

R%28w%29=.23w%2B.37
:
domain: natural numbers {1,2,3...}
range: rational numbers{w:w>=.37}
