x+4 happens to be a factor of the numerator

4. alekos

is that what you're after?

5. campbell_st

looking at the denominator the discontinuity is that value that makes x + 4 = 0 then given you can factor out the discontinuity, it means its a point of discontinuity and not a vertical asymptote...

6. campbell_st

by factoring I mean $\frac{x^2 - 3x -28}{x + 4} = \frac{(x +4)(x -7)}{(x + 4)}$
