Simplify: -3(y+2)^2-5+6y what is the simplified product in standard form

Step-by-step explanation:

Perform the indicated multiplication (squaring):

-3(y^2 + 4y + 4) - 5 + 6y

Continuing with the multiplication:

-3y^2 - 12y - 12 - 5 + 6y

Combiing the y terms in descending order by powers of y:

-3y^2 - 6y - 17

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.
