Question

Find the derivative of f(x) = 6 divided by x at x = -2.

Answer 1

\[6*\frac{ d }{ dx }\frac{ 1 }{ x }\]

Answer 2

What is the d?

Answer 3

that is just how you represent a derivative

Answer 4

Would I just place in 2 for x?

Answer 5

6 times derivative of x^(-1)

Answer 6

-6x^-2

Answer 7

you could also write \(=6(\frac{1}{x})'\)

Answer 8

then where do I go from there?

Answer 9

put in x = -2

Answer 10

but you do need to find the derivative of the section in parentheses first as dan has done

Answer 11

-6 / (-2)^2

Answer 12

So 9?

Answer 13

-6/x*2 = -6/4 = -3/2

Answer 14

-6 / 4

Answer 15

OH okay I thought to divide then square

Answer 16

no problem it was x^2

Answer 17

order of operations there hun

Answer 18

so -3/2

Answer 19

Good luck in calc!

Answer 20

Thank you!!!!!
