one salary scale is modelled by the function s(y) = 25000 + 2250y where s(y) dollars is the salary scale and y is the number of years worked for the company. the employees' union negotiates an increase of $1000 for each employee.

s(y) = 25000 + 2250y
becomes s(y) = 26000 + 2250y

the question is asking me to state a domain and range for this function
how would i get this ?

Question

s(y) = 25000 + 2250y
becomes s(y) = 26000 + 2250y

the question is asking me to state a domain and range for this function
how would i get this ?

Domain and range of Linear equation are R!

anonymous · Answer

the back of the book says that the answer is domain : 0 ≤ y ≤ 45 
range 26000≤ S ≤127250

I guess the question's asking the domain & range of the situation, not the function itself :|

anonymous · Answer

but it only gives me the functions. it doesn't really give me any other numbers. or whatever. :S

zepp · Answer

Have not idea then, there's no way to find how many years the guy worked for that company.

anonymous · Answer

thats true. hmm. i'll just skip the question and ask my teacher when i get back to school.  thanks anyways. :)

zepp · Answer

Np. :)

anonymous · Answer

however if it were asking for the domain and range of the function they would be 
d = all real numbers
r = all real numbers 
correct?

zepp · Answer

Right ^^

anonymous · Answer

okay i'll just write that down for the answer now.
haha thanks again ! :)
