The verification with more steps of limit of a function

And for that the question is to find the limit by the right that is the meaning of the + in the top right of the -1

In that case the graphic before increase indefinitely the Y decrease in the ribbon at the right side of the -1, so I can't say for the ribbon 1st ribbon that is getting closer of '0' by the right, but picking more closer values that realy by the right the function decrease to get '0'.

I gonna use a graphical cientific calculator to do that work for me

And there we have the value decrease until come to the value '0'. Rute Bezerra de Menezes Gondim
