If g:R -->R be two functions defined as f(x)=|x|+x and g(x)=|x|-x for all x belongs to R. Then find fog and gof.

x, \forall x \in R

f, g : R \to R

f (x) = | x | + x

g (x) = | x | - x

x ϵ R

f o g

f o g (5), f o g (- 3)

f

g : R \to R

f (x) = | x | + x

g (x) = | x | - x, \forall x \in R

f o g (x)

f, g : R \to R

f (x) = | x | + x

g (x) = | x | - x, \forall x \in R

(f \circ g) (x)

x < 0
