Question 1019459: Suppose that a car rental agency charges a fixed amount per day plus an amount per mile for renting a car. Heidi rented a car one day and paid $98.50 for 210 miles. On another day she rented a car from the same agency and paid $140.50 for 330 miles. Find the linear function f(x) (where x is in miles and f(x) is in dollars) that the agency could use to determine its daily rental charges.

Question 1019853: A function f is defined for all real numbers and has the following properties.
� f(1) = 2
� f(3) = 10
� f'(2)=4
� For all real numbers a and h, f(a+h)−f(a)=kah+nh^2−2nh (where k and n are
constants).
a) Find the value of k for this function.
b) Find the value of n for this function.
c) Find a formula for f'(x) (this should just be in terms of x, it should not depend on n or k).
d) Using your answer to part c, find a formula for f(x) (this should just be in terms of x, it should not depend on n or k). Hint: Find a function g(x) such that g'(x) = f'(x).Then there is a theorem that there exists a (unique) real number c such that f(x) = g(x) + c.

How do I isolate k and n so that I'm able to find out what they equal? I'm 100% stuck on this problem, and I'm not even sure where to start at any help would be appreciated, thank you for your time.
