Question

i) /R-R defined by f(x)=x+5​

Answer 1

Answer:

f(x)=x 5

y=f(x)=x 5

x=f −1= 5y

Because f −1

is defined for all y∈R, we have that f is surjective or onto.

The implication y 1 =y 2

⇒f −1(y 1 )=f −1 (y 2)

entails that f is injective or one-one.

Being surjective and injective it is bijective (one-to-one).
