Answer:


(F G H)(6) = (1891)/(7)

Explanation:

Explanation:-

Given F(X)=7 x-1

G(X)=x²+1, and

H(X)=(x+ 1 /7)

(F G H)(6) = (F G ) H(6)

=
F G ( 6 + (1)/(7) ) ( ∵ H(X)=(x+ 1 /7)

=
F G ( (43)/(7) )

=
F( ((43)/(7))^(2) +1) ( ∵ G(X)=x²+1)

=
F(((43)^(2)+49 )/(49) )

=
F((1898)/(49) ) (∵ F(X)=7 x-1)


= 7((1898)/(49) )-1


= ((1898)/(7) )-1


= (1898-7)/(7) = (1891)/(7)


(F G H)(6) = (1891)/(7)
