The average value of the function would be $$\large \int_{-3}^{-1} g(x)dx$$ Can you do the integration?

4. ksaimouli Group Title

i exactly did that does not work

5. mathmate Group Title

Sorry, the integral should be divided by (-1- (-3))=2 to get the average value.

6. ksaimouli Group Title

?

7. mathmate Group Title

what did you get?

8. mathmate Group Title

Average value = $$\large \int_a^b f(x)dx / (b-a)$$

9. ksaimouli Group Title

28/6

10. mathmate Group Title

You have the correct answer, but you need to simplify it (14/3) and divide by 2 which comes from (-1-(-3)), the length of interval of integration.

11. mathmate Group Title

In the end, you should get 7/3.

ya thx

13. mathmate Group Title

@oldrin.bataku I think there was a mix-up with the substituted limits of integration.

14. ksaimouli Group Title

i got it

That's good! Keep it up!
