Question

Determine which one of the following options are correct.

f(x)=(x+2)/6 difined for all real numbers

a) is a biyective function, but has no an inverse
b) is a biyective function and its inverse is 6/(x+2)
c) is a biyective function and its inverse is 6x-2 Determine which one of the following options are correct.

f(x)=(x+2)/6 difined for all real numbers

a) is a biyective function, but has no an inverse
b) is a biyective function and its inverse is 6/(x+2)
c) is a biyective function and its inverse is 6x-2 @Mathematics

Answer 1

Inverse is:\[x=\frac{y+2}{6}\]\[y=6x-2\]So c.

Answer 2

you mean that is one function has an inveres is biyective? I dont get it

Answer 3

I thought it was c as well

Answer 4

well, you dont need to know what a bijective function is to answer this since all the choices say the function is bijective. It's actually the first time I've heard the term. But the answer is c.
