Urgent answer! lola plans to publish a magazine. she cannot publish unless she sells at least 100 subscriptions. each subscription costs $20.
the function
r()= 20
represents the amount of revenue she takes in where s is the number of subscribers.
what is the domain of
r(s) in context?
a: all whole numbers
b: all positive rational
numbers
c: all positive integers that are greater than or equal to 100
d: all positive integers that are less than or equal to 100
( explain how you got it cause i have no idea how to do this)

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
