discrete mathematics - How would I show this bijection and also calculate its inverse of the function?

I want to show that f(x) is bijective and calculate it's inverse.




Let f:RR

be defined by f(x)=3x5+7




I understand that a bijection must be injective and surjective but I don't understand how to show it for a function.
