An rock is dropped from a 199-foot platform. Use the projectile formula h = − 16 t 2 + v 0 t + h 0 to determine when the rock hit the ground. [Recall that v 0 is the initial velocity of the object and h 0 is the inital height of the object. Note that since the rock is dropped, v 0 = 0 . ]

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.

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
