Simplify the expression, 4 × 3/4, and determine to which set(s) the answer is a member. I. Natural numbers
II. Whole numbers
III. Integers
IV. Rational numbers

1.) I, II, and III only

2.) I only

3.)I, II, III, IV

4.) I and II only

well the answer to that is xoxoxo

step-by-step explanation:

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.
