Same function , why is there an intersection?

Lucas Vestlund shared this problem 2 years ago

I did the inverse of the top function , 2^(-2x-1)

The one thats unsimplified is the one that i myself came up with, and the second one is the one that wolfram alpha came up with.

The question is why there is an intersection at (1,-1/2),(since its the same function) i suppose this is a bug ? Can you fix this ?

I've attached some pictures of the graphs below.

en general si f==g intersect(f,g,begin,end) responde con una lista de puntos de las funciones

podrían compararse primero y responder que revisen la entrada o que las funciones deben ser diferentes
