Question

Perform the requested operation or operations. f(x) = x minus eight divided by seven.; g(x) = 7x + 8, find g(f(x)).

Answer 1

g(f(x))=x

Explanation:

f(x)=
`(x-8)/(7)`

g(x)=7x+8

g(f(x))=
`g((x-8)/(7))`

=
`7* (x-8)/(7)+8`

=x-8+8

= x

Hence, g(f(x))=x

Answer 2

f(x)=(x-8)/7
g(x) = 7x + 8
g(f(x))-------------- > 7*((x-8)/7)+8----------- >x-8+8=x
the answer is x
