$f(x) = {x}^{2} \times {e}^{ - x}$
​

Answer 1

f(x)=x^2*e^-x.

f’(x)=(x^2*e^-x)’=(x^2)’*e^-x+x^2*(e^-x)’=

2xe^-x-x^2e^-x.

Answer 2

Hey !

Cerinta :

Sa se deriveze.

$f ( x ) = x^{2} * e^{- x}$

Raspuns :

$f ( x ) = x ^ 2 * e ^ - x.$

$f ( x ) = ( x ^ 2 * e ^ {- x} ) = ( x ^ 2 ) * e ^ {- x} + x ^ 2 * ( e ^ {- x} )$

$= 2 * e ^ {x -} -x ^ 2 * e ^ {- x}.$
