Please help algebar 2

Step-by-step explanation:

g(5)= (-5)^2 + 5(-2) - 4

         25 - 10 - 4

         15 - 4 = 11

f(11)= (11)^2 + 2(11) + 3

        121 + 22 + 3

        143 + 3 = 146

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.

d is the answer
