Explanation / Answer

1) f(x) = 6x + 5

g(x) = x - 8

( f- g) = f(x) - g(x)

= 6x + 5 - x + 8

= 5x + 13

domain is ( - infinity , + infinity )

3rd option is correct

2) f(x) = 6x + 5 , g(x) = x - 6

f * g = f(x) * g(x)

= ( 6x + 5) ( x- 6)

= 6x^2 - 36x + 5x - 30

= 6x^2 - 31x - 30

2nd option is correct
