Question

find the slope of the tangent at any point given the following:
a) y=ax^3+bx+c
b) y=a/x

Answer 1

maybe @hartnn can help?

Answer 2

are those two seperate questions

Answer 3

yes, i think so.
additional info: where a,b,c are constants.***

Answer 4

take derivative of ax^3+bx+c

Answer 5

i dont know what is a derivative. i just start calculus on limits

Answer 6

hhmm

Answer 7

how does it tell you to find slope

Answer 8

idk...

Answer 10

recognize anything like this

Answer 11

not really... :(

Answer 12

i do understand the slope thingy. m=\[\triangle y/ \triangle x\]

Answer 13

ugh I know what it is, but it's been too long :(

Answer 14

f(x)-f(a)/x-a but that's like mean value theorem

Answer 15

http://tutorial.math.lamar.edu/Classes/CalcI/Tangents_Rates.aspx this has examples

Answer 16

okay

Answer 17

i know the f(x)-f(a)/x-a theorem thingy that you're talking about
