Question

Find the second derivative of the function f(v)=3v^2+4v-5/v

Answer 1

do you know how to find the first derivative?

Answer 2

kind of not really

Answer 3

do i use the quotient rule?

Answer 4

f'(v)= 6v+4-5v^-2

Answer 5

then take the derivative of that

Answer 6

f''(v)= 6-10v^-3

Answer 7

that's the final answer?

Answer 8

yup

Answer 9

My teacher gave us the answer an he put -10/v^2

Answer 10

to the third power, sorry!

Answer 11

are you sure?
because 3v^2
first derivative= 6v
second derivative= 6
so it should be 6- that

Answer 12

I meant = -10/v^3

Answer 13

6-10/v^3 should be the answer

Answer 14

Alright thanks!

Answer 15

no problem!
