Question

Find ( f o g) for the following functions (refer to photo)

Answer 1

Answer:
`\sqrt{(14)/(5) }` or
`(√(70) )/(5)`

Explanation:

(f o g )(x) means f(g(x)) so take g(x) and put it into f every time you see an x

f(g(x))
`=\sqrt{(2(4+√(x) ))/(5) }`

now plug in 9 for this answer =
`\sqrt{(14)/(5) }` or
`(√(70) )/(5)`
