    B. False. The range is the set of ALL real numbers.

    Step-by-step explanation:

    That is false because we can substitute values of x which will give negative real numbers to give negative values of the function.

    x = - 10 : f (x) = 5 - 40 = - 35.

    The actual range is the set of all real numbers.
