Let f (x) = [x] and g (x ) =|x| ,...

Let ` f (x) = [x] and g (x ) =|x| , AA x in R ` then value of ` gof (( - 5 ) /(3)) + fog (( - 5)/(3)) ` is equal to: ( where ` f _ 0 g (x) = f (g (x)))`.

A

1

B

`-1`

C

`-2`

D

`3`

Text Solution

Verified by Experts

The correct Answer is:
D
`f(x) = [x] , g(x) = |x|`
`g(f(x)) + f(g(x))`
`=[|x|] + [|x|]`
` = |[(-5)/(3)]| + [|(-5)/(3)|]`
` = |-2| + [(5)/(3)] = 2+1 = 3`
