See below for how the domain and the range are calculated

How to determine the domain and the range?

Function, y = -x^4 + 4

The function is given as:

y = -x^4 + 4

See attachment for the graph

From the attached graph, we have:

  • Domain = Set of all real numbers
  • Range = Set of real numbers less than or equal to 4

Function, y = 2x^3 - 1

The function is given as:

y = 2x^3 - 1

See attachment for the graph

From the attached graph, we have:

  • Domain = Set of all real numbers
  • Range = Set of all real numbers

Function, y = ∛(2x + 8)

The function is given as:

y = ∛(2x + 8)

See attachment for the graph

From the attached graph, we have:

  • Domain = Set of all real numbers
  • Range = Set of all real numbers
