The three lines represent the price, in dollars, of three different brands of chocolate bars. Which brand of chocolate bar is the most expensive?

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

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:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
