Let F X be an odd function defined on R and an increasing function. If FA + FB is greater than or equal to 0, then integer a + B is greater than 0

Let F X be an odd function defined on R and an increasing function. If FA + FB is greater than or equal to 0, then integer a + B is greater than 0


An odd function defined on R is an increasing function,
Fa+Fb>=0
Fa>=-Fb=f(-b)
Increasing function
a>=-b
a+b>=0
