Which of the following is an example of a recursive sequence? #1. 1,3,9,27
#2. 2,5,8,11
#3. 2,4,6,10​

1) 1,3,9,27

Step-by-step explanation:

1) is a recursive sequence.

2) is a arithmetic sequence

3) is a geometric sequence

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.
