Selena is graphing the inequality x less-than negative 2. She begins by drawing a number line and placing an open circle at –2. A number line going from negative 7 to positive 3. An open-circle is at negative 2.

Which could be Selena’s next step?
shading the number line to the left of the open circle
shading the number line to the right of the open circle
shading the number line to the right and left of the open circle
shading in the open circle

i need a picure

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.
