Question 841104
f+g(x) means add the functions:

9-6x+x+7=-5x+16

(f + g)(x) = [-5x+16]


(f-g)(x) means subtract g from f:

(9-6x)-(x+7)=-7x+2

(f − g)(x) = [-7x+2]

(fg)(x) means multiply the functions:

(9-6x)(x+7)=9x+63-6x^2-42=

(fg)(x) = [-6x^2+3x+21]


(f/g)(x) means divide g by f:

(9-6x)/(x+7)

(f/g)(x) =[(9-6x)/(x+7)]

Sorry this is a little messy, I'll rewrite the answers here:

(f + g)(x) = [-5x+16]
(f - g)(x) = [-7x+2]
(f * g)(x) = [-6x^2+3x+21]
(f / g)(x)= [(9-6x)/(x+7)]

Hope this helped!
