how does the derivative of an injective and bijective function behave?

injective fn.are one- 1functions which on differentiationalways goesincreasing or decreasing.

bijective functions are thosefunctions which are both one- one and onto.

on differentiation both func.will beprove toas one- one. but to detremine onto function 

C- domain should be equal to range.

No useof derivative!
