What is the inverse function of f(x)=x^5 + 2x^3 + x + 1?

I know I have to solve for x, i'm just confused how to with such high powers.





Thank you!What is the inverse function of f(x)=x^5 + 2x^3 + x + 1?
To find the inverse of the function, interchange the variables and solve for f^(-1)(x).





x=f^-1(x)^5+2f^-1(x)鲁+f^-1(x)+1





Since f^-1(x) is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.





f^-1(x)^5+2f^-1(x)鲁+f^-1(x)+1=x
