When doing shifts on functions we can consider that there are vertical and horizontal shifts.
When the function has a change in the form
[tex]y=(a)^{x\pm b^{}}[/tex]there is a horizontal shift happening, if it is positive then the graph moves b units to the left and if it is negative the function moves b units to the right.
When the change is in the form
[tex]y=a^x\pm b[/tex]there is a vertical shift happening, if it is positive then the graph moves b units up, and if it is negative the function moves b units down.
in this case, the graph is moving 1 unit up.
the correct answer option is
