Is this question a correct one that can be solved or is it a wrong question, because it makes no sense to
we throw an object upward from the top of a 1200ft building. the height of the object, (measured in feet) t seconds after we threw it is
h+16t 2 + 160t + 1200
a) where is the object 3 seconds after we threw it?
b) how long does it take the object to hit the ground?

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.
