Sketch the vector field f(r) = -r / ||r||^3 in the xy-plane. select all that apply. a. the lengths of the vectors decrease as you move away from the origin. b. all the vectors point towards the origin. c. the length of each vector is 1. d. all the vectors point in the same direction. all the vectors point away from the origin.

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.
