Question

f:R-R,f(x)=2x-1÷3 is bijective,justify​

Answer 1

Answer:

2x-1/3=2y-1/3

2x-1=2y-1

2x=2y

x=y

hence tge given equation is bijective

Answer 2

Answer:

yes it is a bijective only

Step-by-step explanation:

because is can consider both one one and onto function

one one function

where

f(x)1=f(x)2

2x1-1÷3=2x2-1÷3

all cancelled by each other

x1=x2

so that the function is one one

onto

range of function =codomain of the function

range of f ={set of all real numbers }

Co domain of f={set of real numbers }

so the function is onto

● so that function is bijective
