F(x) = 4x + 7x2 - 2x - 1 g(x) = 4x - 2
Find (f - g)(x).
A. (f - g)(x) = 4.3 + 7x2 + 2x - 3
B. (f - g)(x) = 483 + 702 6x
3.
c. (f-g)(x) = 4x3 + 7x2 + 2x +1
O D. (f-g)(x) = 4x3 + 722
6x +1
Please help

idk

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.
