    interval meaning a space between 2 numbers increasing meaning the function is rising decreasing meaning the function is going down so use your finger and follow the graph from its leftmost point all the way to its rightmost point

    if it's going up, it's increasing on that interval, if it's going down it's decreasing on that interval

    anyhow, it's increasing on \((- \infty ,5) \) and decreasing on \((5,\infty)\)
