if find g(4)

@agent0smith can u help?

4. onegirl

@Spacelimbus can u help please?

5. Numb3r1

I've got this.

6. onegirl

ok can u help?

7. Numb3r1

$g(x)=\int\limits_{1}^{x} f(t)dt$ Based on that, it's just the area under f(x) from 1 to 4. That should be easy to find geometrically.

8. onegirl

okay i got 3 is that correct?

9. onegirl

@SithsAndGiggles can u help?

10. Numb3r1

I count three boxes and three triangles. That's three and three halves.

11. SithsAndGiggles

@Numb3r1, you mean 4 and a half.

12. Numb3r1

I like to leave a little simplification for them to do, but yes.

13. SithsAndGiggles

Oh, I misread that. Sorry

14. SithsAndGiggles

I thought you had said 3 and a half.

15. onegirl

so its 4.5

16. Numb3r1

Yup! If you have a graph and can just count the integral, do.
