If f (x) is an odd function on R, and if x > 0, f (x) = the third power of X + 1, then the expression of F (x) is

If f (x) is an odd function on R, and if x > 0, f (x) = the third power of X + 1, then the expression of F (x) is

f(-x)=-x^3+1
F (x) is an odd function on R, i.e
f(-x)=-f(x)
f(-x)=-x^3+1=-f(x)
f(x)=x^3-1
x^3+1 ,x>0
f(x)= 0 ,x=0
x^3-1 ,x
