The value of the second derivative for

is neither positive nor negative, so you can't tell whether this point is a minimum or a maximum. You need to check the values of the first derivative around the point.
But the value of

is always positive for

. That means at

there's neither minimum nor maximum.
The maximum must be then at either of the endpoints of the interval
![[-2,1]](https://tex.z-dn.net/?f=%5B-2%2C1%5D)
.
The function

is increasing in its entire domain, so the maximum value is at the right endpoint of the interval.
If the sides are close together, its acute.
Sorry for the delay! The transformation would be a translation over the x-axis of 10 points.
Answer:
There will be 128 organisms after 30 minutes.
Step-by-step explanation:
30/5=6
1.) 2*2=4
2.) 4*2=8
3.) 8*2=16
4.) 16*2=32
5.) 32*2=64
6.) 64*2=128
