Answer:
0 is an inflection point
1/4 is a local maximum.
Step-by-step explanation:
To begin with you find the first derivative of the function and get that

to find the critical points you equal the first derivative to 0 and get that

To find if they are maximums or local minimums you use the second derivative.

since
is neither an inflection point, and since
then 1/4 is a maximum.
Step-by-step explanation:
Well if you dont understand something ask a teacher for help or study on a topic that you struggle with for example math try looking up different math questions and solving them or ask a teacher is you can have pratice questions or problems then show it to him/her so they can check to see if you are right. Hope that help unless you dont understand a certain question that I might have missed.
Answer:
C
Step-by-step explanation:
<span>42=-2d+6
Here, to find d, you need to separate it on one side.
First, subtract 6 from both sides.
42-6 = -2d + 6 - 6
36 = -2d
Now divide both sides by -2.
36/-2 = -2/-2d
-18 = d
The answer to this problem is -18, or d = -18.</span>
