Let f x 7 x and gx x 1 find9 g Solutiongiven f x 7 x an

Let f (x) = 7 ? x and g(x) = x – 1

find(-9) g

given f (x) = 7 x and g(x) = x – 1

(f_/g)(-9)=(f(-9))_/(g(-9))

(f_/g)(-9)=(7-(-9))_/((-9)-1)

(f_/g)(-9)=(7+9)_/(-9-1)

(f_/g)(-9)=(16)_/(-10)

(f_/g)(-9)= - 8_/5

------------------------------------------

(f_/g)(x)=(f(x))_/(g(x))

(f_/g)(x) is defined when g(x)0

=>x-10

=>x1

domain of (f_/g) is (-,1)U(1,)
