Which polynomial function has a leading coefficient of 3 and roots -4,1, and 2, all with multiplicity 1? of(x) = 3(x + 4)(x - 1)(x - 2) of(x) = (x - 3)(x + 4)(x-7)(x-2) of(x) = (x − 3)(x + 4)(x - 1)(x + 1)(x - 2) of(x) = 3(x + 4)(x - 1)(x + 1)(x - 2)

For this case, we can discard options B and C because they do not have coefficients. Also, we discard option D because it has 4 roots given by -4.1, -1,2 each with multiplicity "1".

The multiplicity indicates the number of times a root is repeated.

Then, we have that the correct option is option A, we have a coefficient of "3", in addition to three roots (-4,1,2) with multiplicity "1", because they only repeat once.

Option A

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
