The function f(x) is graphed below. What is the equation of the line that is perpendicular to f(x) and passes through the point (4, –6)?

A. 4x + 3y = –2
B. 3x + 4y = –12
C. 4x – 3y = 34
D. 3x – 4y = 36

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: check all that apply, where the options?

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
