Find the function's maximum and minimum points

• no maximum

  absolute minimum @ (-1,-4)

• no minimum

  maximum (2, 6)

• no maximum

  relative minimum @ (-1, -4)

• no maximum

  relative minimum @ (0, -3)

Identify the function's domain and range.

• domain (-∞,∞) and range (-∞,∞)

• domain (-∞, ∞) and range (-4,∞)

• domain (-∞,∞) and range [-4,∞)

• domain [-3, 1] and range [-4,∞)

Where is the function increasing and where is it decreasing?
