# Graph y=1/(3^x)

Find where the expression is undefined.
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
The vertical asymptotes occur at areas of infinite discontinuity.
No Vertical Asymptotes
Since its numerator approaches a real number while its denominator is unbounded, the fraction approaches .
List the horizontal asymptotes:
There is no oblique asymptote because the degree of the numerator is less than or equal to the degree of the denominator.
No Oblique Asymptotes
This is the set of all asymptotes.
No Vertical Asymptotes
Horizontal Asymptotes:
