Question

problem posted in correct format below

Answer 1

find the derivative of \[x^3 + 2x^2 + 3x + 7\]
h\[\rightarrow h\]

Answer 2

limit as h approaches 0

Answer 3

correct format eh .... :)

Answer 4

lol i tried
i saw yall come and tried to do it quickly

Answer 5

what is the h, is it division? or are you trying to perform some first principles application?

Answer 6

the limit is h->0
im supposed to use the formula of \[\frac{ f(x+h) - f(x) }{ h }\]

Answer 7

im supposed to solve it the 'long' way and use the shortcut to check my answer, if it would be easier i can just post a picture of my work and you can look to see if you can see where i made a mistake? im unable to find my mistake

Answer 8

then you have alot of work ahead of you :)

Answer 9

expanding those x+h parts is not hard, just tedious

Answer 10

post your work

Answer 11

wokring on it

Answer 12

hope its readable where i x'ed the numbers oiut

Answer 13

and i mean if i did it totally wrong, obviously let me know haha

Answer 14

3x^2 + 4x + 3 is right

Answer 15

ooh wow.. when i did the shortcut i messed up

Answer 16

fr some reason when doing the shortcut to move the exponent down i subtracted 1 from that too..
ha im stupid

Answer 17

its becasue youre trying to remember a rule instead of doing math

Answer 18

yeah ik but for my test, its required me remember the "rules"

Answer 19

practice helps the memory stick

Answer 20

drop then subtract

Answer 21

we have to work a problem and write step by step explaining what to do

Answer 22

yeah ik, thanks a bunch. that explains why i couldnt find a mistake when looking over it again

Answer 23

x^3 to 3x^(3-1)

Answer 24

yeah i have that example written in my notes :D thanks again

Answer 25

gotta do a few more like this before i can move on
