    Answer:

    Domain(-infinity,+infinity)

    Range=f(x) >or= – 34

    Step-by-step explanation:

    Domain for every parabola the domain is (-infinity, +infinity) unless there are any restrictions

    Range we look at the y value of the maximum point or minimum points

    We find it by finding the turning point

    F'(x) =2x+6

    0=2x+6

    -6=2x

    x=-3

    F(-3)=(-3)^2+6(-3)-23

    =-34

    So all value that exist on the f(x) must be greater or =-34
