Answer:
(50,55,60,....)
Step-by-step explanation:
Given that a health insurance plan has a $50 enrollment fee and a copayment of $5 for each doctor visit.
The function f(x) = 5x + 50 gives the cost of x doctor visits
Here x is the no of visits.
No of visits is an independent variable while f(x) total cost is a dependent variable on x
slope = 5 which indicates for each visit extra, extra cost is 5 dollars
Enrollment fee = 50 = fixed cost
Hence domain would be
x =0,1,2,3.....
So range is
(50,55,60,....)
