gof exists, when :

If and g are deppcreasing functions such that gof exists then gof is

If f is decreasing and g is increasing functions such that gof exists then gof is

Capillary does not exist when the liquid is at

Capillary action does not exist when the liquid is at

Lim f(x) does not exist when

Let f: A to B and g: B to C be two functions. Then; if gof is onto then g is onto; if gof is one one then f is one-one and if gof is onto and g is one one then f is onto and if gof is one one and f is onto then g is one one.
