Answer 1

This?
\[f(x) = \frac{{x^2-3x-28} }{ x+4 }\]

Answer 2

Are you asking where the discontinuity is, or what kind it is?

Answer 4

ok. well just set the denominator equal to 0 to get the x-coordinate

Answer 5

you'd have to factor and cancel before you can substitute to get the y

Answer 6

how would i do that
