Question

find if function bijection without graph.
f(x)=(x²+1)/(x²+2)​

Answer 1

Answer:

not bijection

Step-by-step explanation:

Bijection is called ono to one and onto function

if x = 1, f(1) = 2/3

x= 2, f(2) = 5/6

it is one - one function

It is not onto function

so, It is not bijection.
