The function `f(x)=(2x-1)/(x-2)(xne2)` is such thatA. it is inverse of itselfB. decreases in `(-infty,2)` and `(2,infty)`C. it has a graph entirely above x-axisD. `underset(xto0^(+))(lim)f(e^(x^(-1))=2`

Answer» Correct Answer - A::B::D
`f(x)=2+(3)/(x-2)` is bijective
`f^(-1)(x)=2+(3)/(x-2)`
`underset(xto0)(lim)f(e^((1)/(x)))=2`
