  • What is the general form of a constant function?
    The general form is f(x) = c, where c is any constant number.
  • What is the domain of the constant function f(x) = c?
    The domain is all real numbers, from negative infinity to positive infinity.
  • What is the range of the constant function f(x) = c?
    The range is just the constant value c.
  • What does the identity function f(x) = x do to its input?
    It returns the same value as the input; whatever you put in, you get out.
  • What are the domain and range of the identity function f(x) = x?
    Both the domain and range are all real numbers.
  • What is the general form of the square function?
    The general form is f(x) = x^2.
  • What is the shape of the graph of the square function?
    It forms a parabola, which is a bowl-like shape.
  • What is the domain of the square function f(x) = x^2?
    The domain is all real numbers.
  • What is the range of the square function f(x) = x^2?
    The range is from 0 to positive infinity, including 0.
  • What is the general form of the cube function?
    The general form is f(x) = x^3.
  • What are the domain and range of the cube function f(x) = x^3?
    Both the domain and range are all real numbers.
  • What is the general form of the square root function?
    The general form is f(x) = √x.
  • What is the domain of the square root function f(x) = √x?
    The domain is from 0 to positive infinity, including 0.
  • What is the range of the square root function f(x) = √x?
    The range is from 0 to positive infinity, including 0.
  • What are the domain and range of the cube root function f(x) = ∛x?
    Both the domain and range are all real numbers.
