If Q is the set of all rational numbers, and `f:Qto Q` is defined by `f(x)=5x+4,AAx in Q`, show that f is a bijection.

If Q is the set of rational numbers and a function f:Q to Q is defined as f(x)=5x-4, x in Q , then show that f is one-one and onto.

If f:Q to Q is defined by f(x) = 5x+4 , find f^(-1) .
