    for y= -2x+1 and g(x) = x+2
    D and R ~(-infinity; + infinity)

    for h(x) = -3x^2
    D~(-infinity; +infinity)
    R~( +infinity ;0]

    1) domain is all real numbers
    range is all real numbers

    2) domain is all real numbers
    range is all real numbers

    3) domain is all real numbers
    range is all real numbers less than or equal to zero.

  3. the domain and range of all three is all real numbers because there are no fractions. there are only problems witht the domain and range when there are fractions, to keep it simple.
