Find the next term of the square 16,9,2,-5

- 12

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence.

9 - 16 = 2 - 9 = - 5 - 2 = - 7

Thus to find the next term subtract 7 from the previous term, that is

- 5 - 7 = - 12

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.
