The equation and graph show the cost to rent movies from two different companies. The cost is a function of
the number of movies rented.
Which description best compares the two functions?
Company 1
Company 2
m=movies, d=dollars
d = 3m + 5
Movie
Company 1 adds a higher
initial fee to the rental cost.
There is a higher rate of
change at Company 1.
There is a higher rate of
change at Company 2.
It costs more to rent movies
from Company 2.

step-by-step explanation:

their is no graph showing

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.
