C

Step-by-step explanation:

whenever you see a (as in ax^2 + bx+c) as a number other than 1, you should see if you can factor that out

2(6x^2 -x -1)

= 2(3x+1) (2x-1)

C

Step-by-step explanation:

The answer is c because when it says (f/g)(x) it means f(x)/g(x). Which means that it would be c. For the domain, it can be all real numbers instead of -1/6. Why? Because if you multiply 6*-1/6, you get -1 and -1+1 equals 0. We already know that you can't divide anything by 0 and it will be undefined so x cannot be -1/6.
