yes with cream please

Answer 3

sorry - silly joke!

Answer 4

haha I have an exam
and im LOST

Answer 5

Where to begin?

Answer 6

its basic for u guys probably
derivatives

Answer 7

Do you understand the definition of a derivative?

Answer 8

yes

Answer 9

or are you having trouble with the rules on how to take the derivative

Answer 10

k like this question, commute f(c+h)-f(c) at indicated points f(x)=-2+1; c=2

Answer 11

sorry im slow at typing this stuff

Answer 12

its fine:) ok so that is the definition of a derivative,
f(c+h) means replace 'x' with 'c+h' in the equation, and
f(c) means replace 'x' with 'c' in the equation. Ignore c=2 for the moment

Answer 13

and this website is a little tricky to figure out:P

Answer 14

hmmm k?

Answer 15

is there suppose to be an x in the equation f(x) = -2+1 ?

Answer 16

oops yes, -2x+1

Answer 17

ok. taking f(c+h) - f(c) = [-2(c+h)+1] - [-2(c)+1]

Answer 18

why [-2(c)+1]

Answer 19

because its f(c+h) - "f(c)" and f(c) = -2(c)+1

Answer 20

k

Answer 21

if i remember the formula correctly i believe we are to take
\[\lim_{h \rightarrow 0} [f(c+h)-f(c)]/h\]

Answer 22

k? lol im so lost

Answer 23

is that the quotient rule

Answer 24

here let me send you to an online area that explains this better. then after reading that section come back and ask any other question you have that wasn't answered:

Answer 25

thnx:)

Answer 26

u just starting calculus shenys?

Answer 27

it can be difficult at first but once you grasp the concepts it is not so hard and is quite interesting

Answer 28
