Graph the function y = 2^x + 1.

This will be like the function y = 2^x, but each y value will be 1 bigger than in that function. y is a master of one-upsmanship.

We take the graph of y = 2^x and move it up by one:

Since we've moved the graph up by 1, the asymptote has moved up by 1 as well. It used an asymptote bag to move all its things.

The asymptote is now the line y = 1.
