The particles in an object move very quickly and are spread apart. Then they move slower and get slower and get closer together but do not form regular and organized patterns. What change of state occured? How do you know?

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

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.
