Freday • The equation y = 2.13 represents the relationship between X, the number of tickets, and
y, the price.
Which ordered pairs represent a number of tickets and the corresponding
price in the given equation? Choose ALL that apply.
(3,6.3)
(6.3, 3)
(2.1, 10.5)
(7, 14.7)
(10.5, 2.1)
(14.7, 7)

the square root of what number? if you add that, then someone will probably answer the question.

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.
