mark me brainleast and follow me

Step-by-step explanation:

It is a chemical disinfection method that uses various types of chlorine or chlorine-containing substances for the oxidation and disinfection of what will be the potable water source.

Answer 2

f(x)+2f(1−x)=x

2

+2⋯⋯(i)

Put x=1−x

⇒f(1−x)+2f(x)=(1−x)

2

+2

Multiply by 2

⇒2f(1−x)+4f(x)=2(1−x)

2

+4⋯⋯(ii)

Subtract (ii) from (i)

−3f(x)=x

2

−2−2(1−x)

2

−3f(x)=x

2

−2−2x

2

+4x

−3f(x)=−(x

2

−4x+4)

f(x)=−

3

(x−2)
