Status: Waiting for your responses.

Determine the asymptotes and possible hole for this rational function.

f(x) =   x + 1
x2 + 3x - 18

Choose the correct type of solution set.

Type 1

1 horizontal asymptote
1 vertical asymptote
0 holes

Type 2

1 horizontal asymptote
1 vertical asymptote
1 hole

Type 3

1 horizontal asymptote
2 vertical asymptotes
0 holes

Record your responses for asymptotes and the hole, if applicable.

The horizontal asymptote is at y =
The first (or only) vertical asymptote is at x =
The second vertical asymptote is at x =
The hole is at x =
