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
anonymous
  • anonymous
So is it increasing right?
anonymous

I think i'm starting to understand

not always, do you see the vertex of the parabola?
anonymous
  • anonymous
at a certain point it starts going down
anonymous
  • anonymous
anyhow, it's increasing on \((- \infty ,5) \) and decreasing on \((5,\infty)\)
