Question

Please urgent help with 3 and 4!!!!

Answer 1

3) option C

Explanation:

we have from the statement:

f(x)=
`(√(x+3))/(x)`

g(x)=
`(√(x+3))/(2x)`

so we have:

(f.g)(x)=
`(√(x+3))/(x)` *
`(√(x+3))/(2x)`

(f.g)(x)=
`((√(x+3))^(2) )/(x*2x)`

(f.g)(x)=
`(x+3)/(2x^(2))`

the answer is option C
