You plan to rent a car from XYZ Car Rental Company for a flat rate of $35 a day. In addition to $35 per day, you must pay a $10 insurance fee per day for 1–3 days. If you keep the car longer than 3 days, there is a $5 insurance fee per day. Write a piecewise-defined function that models this function.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

probably .5
