Abby will receive a cash prize when she earns 300 bonus points at the video shop. Abby receives 5 bonus points every time she rents a recent release video
at the video store, plus a 60-point bonus for becoming a member. The total
number of bonus points, B is given by B = 57-60, where n is the number of
videos being rented. How many videos must Abby rent to receive her cash
prize?

g

step-by-step explanation:

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.
