What is the Inverse of the Function f(x) = e^x + e^(-x) + 1?

In summary, the inverse of f(x)=e^x + e^-x+1 is given by the function g(x)=ln(x+1). To find the inverse, switch the positions of x and y in the equation and solve for y. The inverse function g(x)=ln(x+1) is a one-to-one function with a domain of all real numbers greater than or equal to -1 and a range of all real numbers. To graph the inverse function, plot the points (0,0) and (1,0) and use the inverse function to find the corresponding points for other values of x. Connect these points to create the graph of the inverse function.

Try solving $$e^x+e^{-x}+1=y.$$

Convert problem into a quadratic equation by [itex]u=e^x,\ u^2+1+u(1-y)=0[/itex]. Get u as a function of y, then x=ln(u).
