Graph (e^x+e^(-x))/2
ex+e-x2
Step 1
Find where the expression ex+e-x2 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.
Step 2
The vertical asymptotes occur at areas of infinite discontinuity.
No Vertical Asymptotes
Step 3
Since the limit does not exist, there are no horizontal asymptotes.
No Horizontal Asymptotes
Step 4
Since there is no remainder from the polynomial division, there are no oblique asymptotes.
No Oblique Asymptotes
Step 5
This is the set of all asymptotes.
No Vertical Asymptotes
No Horizontal Asymptotes
No Oblique Asymptotes
