    A. x = 3 B. x =
    C. y = 0 D. x = 0
    Hint

  5.   In a certain job, the function represents the amount of hours worked x in relation to the amount of stress f(x) felt by the workers. For what values of x does this graph have meaning?
    A. for all values of x B. for and x > 40, because stress is a non-negative quantity
    C. for and x < 40 D. for
