Question

derivatives

Answer 1

find the derivative of f(x)= -3/x at x=-4

Answer 2

The derivative of a function of a real variable measures the sensitivity to change of a quantity (a function or dependent variable) which is determined by another quantity (the independent variable).

Answer 3

.-. what now

Answer 4

Thanks for the meaning of derivative beastiman :)

lovely, do you know how to take the derivative of x^n ?

Answer 5

would it be -4^2 since x=-4?

Answer 6

just kidding -4^n i didnt mean 2

Answer 7

forget about x=-4

can you just take the derivative of
-1/x ?

Answer 8

is this better
The derivative itself is merely a contract between two or more parties. Its value is determined by fluctuations in the underlying asset. The most common underlying assets include stocks, bonds, commodities, currencies, interest rates and market indexes. Most derivatives are characterized by high leverage.

Answer 9

im so confused.... and no..... how do i divide -1 and x? wouldnt i just get 1x?

Answer 10

ok,
can you express 1/x in exponent form, as x^n ?
n= ... ?

Answer 11

.-. 1/x^n

Answer 12

1/x^n will be x^-n

1/x will be ... ?

Answer 13

where is n?

Answer 14

In mathematics, the derivative is a way to represent rate of change, that is - the amount by which a function is changing at one given point. For functions that act on the real numbers, it is the slope of the tangent line at a point on a graph. The derivative is often written using "dy over dx" (meaning the difference in y divided by the difference in x :)

Answer 15

he is talking in general
