What is the product of (2p + 7)(3p2 + 4p – 3)? A.6p3 + 29p2 – 34p + 21
B.6p3 + 29p2 – 22p + 21
C.6p3 + 29p2 + 22p – 21
D.6p3 + 29p2 + 34p – 21

C

Step-by-step explanation:

6p3 + 8p2 - 6p + 21p2 +28p -21

6p3 + 29p2 + 22p - 21

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.
