5. Carlos took seven years to pay off his loan by making identical quarterly payments. The loan had a principal of $24,375
and 6.49% interest, compounded quarterly. Carlos paid a total of $30.821.67. How much did Carlos pay in service
charges? Round all dollar values to the nearest cent.

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.
