#### Explanation:

**Vertical asymptotes**

substitute values of x that will make the denominator 0.

to do that you must factor, the denominator to obtain

then the values that would make this denominator 0 are

therefore, the equations of the asymptotes are,

graph{(x+1)/(x^2+3x-4) [-6.244, 6.243, -3.12, 3.123]}

Note there are no horizontal asymptotes.
