Lol some words you really need to proof read before you submit. I'm assuming you meant "dock" XD
If you are referring those last 3 apps to the right of the dock? You have recent apps option on.
To turn off:
- Open the Settings app.
- Tap on General.
- Select Multitasking & Dock.
- Scroll down to the Dock section.
- Slide the toggle next to Show suggested and recent apps into the Off position.
