Question

HELLLLP PLEASE!!!(:
problem attached below.

Answer 1

Help? @myininaya

Answer 2

what is this for?

Answer 3

Calc 1. @FibonacciChick666

Answer 4

I mean like what is it for?

Answer 5

It looks like a test

Answer 6

homework assignment. @FibonacciChick666

Answer 7

Please don't tag me every time. And ok, so do you have any ideas on how to begin?

Answer 8

I mean I can guess. that the highest vertex is the max and the lowest vertex is the min?

Answer 9

Well, let's start from a more basic place. The graph, is it of the 1st deriv. or no deriv?

Answer 10

the 1st derivative.

Answer 11

ok good, so now, what does the first deriv tell us about the function?

Answer 12

That at x=2 and x=6 is positive and at x=4 and x=8 is negative?

Answer 13

more general

Answer 14

in my case where its negative on the derivative, it's a positive on the function

Answer 15

uhm, in general the first derivative tells us the _____ at each point of the function.

Answer 16

pos/neg? concave up/down?

Answer 17

no

Answer 18

one word

Answer 19

function?

Answer 20

it's really really basic

Answer 21

direction?

Answer 22

no, ok here rwatch this: https://www.khanacademy.org/math/differential-calculus/taking-derivatives/derivative_intro/v/calculus--derivatives-1

Answer 23

slope

Answer 24

?

Answer 25

yep

Answer 26

so now, the derivative is the slope of our function

Answer 27

okay.

Answer 28

when the derivative is positive, what does that tell us about our graph?

Answer 29

it has a negative slope?

Answer 30

no, the derivative= slope,

Answer 31

when it's positive theres a concave down?

Answer 32

there's a max?

Answer 33

uhm I think you are highly confused, I recommend watching these https://www.khanacademy.org/math/differential-calculus/derivative_applications/critical_points_graphing/v/minima--maxima-and-critical-points

Answer 34

or if you've been doing this for a long time, take a break

Answer 35

or you can help explain it to me/ (:

Answer 36

then watch those, They will reiterate the concepts

Answer 37

alright. thanks.

Answer 38

I can't explain calc from scratch, that would take a long time

Answer 39

as you can see at least 20 minutes of video is dedicated to the concepts you need

Answer 40

you don't have to explain from the beginning... but okay. cool. thanks.

Answer 41

so if you watch those, then come back I can help, but without fully understanding what the first derivative is, you will not be able to do this problem
