Let f(x)= -4x-1 and g(x)= x^2+1.
Find (f x g)(7).
(f x g)(7) = __

Step-by-step explanation:

Let f(x)= -4x-1 and

g(x)= x^2+1.

(f.g)(x) = (-4x-1)(x²+1)

-4x(x²+1)-1(x²+1)

-4x³-4x-x²-1

(f.g)(x)= -4x³-x²-4x-1

(f.g)(7) =-4(7)³-(7)²-4(7)-1= -4(343)-49-28-1 = -1372-77-1= -1372-78 = -1450

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
