According to your solution they are not intersection point, P(α, β) and Q(β,α) intersect only if they are same point's coordinate because they are intersection point of f and inv f. So α = β and slope of a single point is undefined.

If P(a,b) and Q(c,d) are two different intersection point of f and inv f then should lie on y = x. and
slope of PQ will be 1.

Do lnx and e^x intersect each-other? how and where ?
