Rational Functions Removable Discontinuities

Determine the type(s) and location(s) of all discontinuities

• jump at x = -3, infinite at x = 2, removable at x = 2.

• jump at x = -3, removable at x = 2, removable at x = 4.

• removable at x = -3, removable at x = 2, removable at x = 4.

• jump at x = -3, removable at x = 2, jump at x = 4.

Find the vertical asymptotes and holes of the function.

• Holes: None;

  VA: x = 1, -3

• Holes: x = -3;

  VA: x = 1

• Holes: x = -3, 1

  VA: None

• Holes: x = 1

  VA: x = -3
