What is the range of the function on the graph? all real numbers
all real numbers less than or equal to –1
all real numbers less than or equal to 3
all real numbers less than or equal to 0

answer: (1,3) and (-2,0) i think.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

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.
