2. Which of the following is equivalent to the expression 9x2 - 16? A. (3x - 4)2 B. (9x - 4)(9x + 4) C. (3x - 8)(3x + 8) D. (3x - 4)(3x + 4)

Answer

( 3x + 4) its 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.
