Question

use the given information to find f ' (2)
g(2)= 2 g ' (2)= -4
h(2)= -1 h ' (2) = 4
f(x)= g(x)/h(x)

Answer 1

i know you use the chain rule h ' (x)= f ' [g(x)] * g ' (x) im just a little confused on how

Answer 2

f is a quotient, what is the quotient rule?

Answer 3

this isnt a chain rule perse

Answer 4

the quotient rule is v/u= vu' - uv'/(v)^2 but our teacher shows us problem like this using the other rule i put on my 1st reply not the quotient rule

Answer 5

this is a quotient, use the quotient rule

Answer 6

f = g/h

f' = (gh' - g'h)/h^2

they give you g,h,g',h' to fill in

Answer 7

thats what i thought but when a kid ask about using the quotient rule in class he told us not quit thats why i was confused

Answer 8

if f=g(h) we use a chain rule

if f = gh we use a product rule

if f = g/h we use a quotient rule

if f = g+h we use whatever rules apply to g and h

Answer 9

but thank you ill try your way

Answer 10

yeah web assign told me it was wrong maybe i did something wrong who knows

Answer 11

2(4) - (-1)(-4)
------------
(-1)^2

so 8-4 is?

Answer 12

well, 4-8

Answer 13

4 but web assign said that was wrong

Answer 14

i got my top quotient rule backwards ... hg' - h'g

Answer 15

ok yeah i did 8-4 not 4-8

Answer 16

i usually define it as but but

t/b = bt'-b't/b^2

Answer 17

thank you

Answer 18

youre welcome
