was there an answer to question 9 in the multis.

[6.0, 6.2) ->the area under the curve is non-zero, so it couldnt include 6.0

and

[6.2, 6.4) -> the area was 2*0.1 = 0.2 less that 0.2 so it can't be this

and the other two were for decreasing function but it was increasing?

oh. for 9 i was thinking f'(x) is positive so its increasing, so it can't be including 6.0, so its [6.2,6.4)

yeah but i did that as well. then someone told be it has 2 on the y axis meaning the area under the rectangle is 2*0.1 =0.2 but the area of the rectangle overestimates so it must be less than 6.2 if that makes sense?

huh so it's less than 6.2 but can't be 6.0 (increasing function)? that eliminates A and B right? unless A was (6.2...)

i mean even if so (6.2 to 6.4) is already too large of a value.

so i don't think any are right. and obviously. The other 2 were in the 5's which is wrong because it wasnt decreasing
