Use the vertical method to multiply (4a^3-2a+3a^2+1) and (3-2a+a^2). What would be the value of A? a. -4a
b. -4a^2
c. 4a
d. 4a^2

step-by-step explanation:

1 is c

2 is a

3 is a

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.
