so for 1.)

f(0) = 3^0 + 1
f(0) = 2 ? y intercept.

domain is all real numbers, x can be any negative number as well, eg 3^(-1) + 1 = 4/3

so on the graph for coordinate -1 the corresponding y value is 4/3.

etc, and as you input x as x ? -infinity you get the asymptote, which is 3^-99999 + 1,

and if you put x ? infinity you get the other asymptote
