we have the two function :

f(x) = 1/x  and g(x) = 3 / (x+3)

Find

(f + g)(x) =(4x + 3 )/ (x² +3x)

Find the domain of

(f + g)(x).

D(f+g) = ]-infini , -3[U]-3 , 0[ U ] 0 , +infini[

Find

(f − g)(x) = (3 - 2x) / (x² +3x)

Find the domain of

(f − g)(x).

D(f- g) = ]-infini , -3[U]-3 , 0[ U ] 0 , +infini[

Find

(fg)(x) = 1 / (x² + 3x)

Find the domain of

(fg)(x).

D(fg) = ]-infini , -3[U]-3 , 0[ U ] 0 , +infini[

Find

(f/g)(x).  =( x + 3 )/ 3x

Find the domain of

 f g
(x).

D(f/g) = ]-infini ,  0[ U ] 0 , +infini[

Good Luck
