    Answer:

    2. increasing when x > 0

    the result of root is a positive number

    and since there is no value of neg number in roots so it’s increasing when x>0

    plus in zero it self has a positive number (0,8)

    but u cannot find either it’s increasing or decreasing in zero bcoz in first derivative test

    when x =0

    y= not defined
