derivative of e^-x?

Question

and second derivative too please

Answer 1

For all a, derivative of e^ax is a e^ax

In this case, a = -1

So derivative of e^-x is -e^-x

Answer 2

derivative of e^-x
let y = e^-x
y ' = e^-x (-1) = -e^-x

Answer 3

derivative of e^x = e^x

derivative of e^-x = - e^-x

Answer 4

d/dx e^-x = -e^-x
Expontental rule, multiply the coefficient of the exponet with the function and the coefficient remains the same

If it had been d/dx of e^(-1/4x) the the answer would have been -1/4e^(-1/4x)

Answer 5

y= e^-x
y'= (-1)e^-x=-e^-x
y"= (-1)(-1)e^-x =e^-x
