Which of the following systems of inequalities would produce the region indicated on the graph below?

O A. VS-x+4; y > x+ 2; y 20:20
O B. VS-x+ 4; y 2x+ 2; y 20:120
OC. VS-x+4; v O D. VS-x+4; v 5x+ 2; y 20:x20

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

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.
