Question

g(x)= 5/x

f(x)=7+x/2

give the simplified expression of g(f(x))

Answer 1

Plug in in the x of f(x) into g(x)

g(f(x)) = 5/(7 + x/2)

Answer 2

\[\ g(f(x)) = \frac{ 5 }{ 7+\frac{ x }{ 2 } }\]
\[g(f(x) )= \frac{ 5 }{ \frac{ 14+x }{ 2 } }\]
\[g(f(x)) = \frac{ 10 }{14+x }\]

Answer 3

is that simplified fizic?

Answer 4

No lol, you have to do it xD
