Answer:
Option B is correct.
The domain of the function h(x) is:
Step-by-step explanation:
Domain states that the complete set of all the possible values of the independent variable where function is defined.
Given the function:
To find the excluded value in the domain of the function.
equate the denominator to 0 and solve for x.
i.e
⇒x = 0 and
⇒x = 0 and
or
x = 0 and
So, the domain of the function h(x) is the set of all real number except x = 0 and
Therefore, the domain of the function h(x) is:
We will use the product rule:
d/dx( f(x) · g(x) ) = f´( x ) g( x ) + g´( x ) f( x ) ( and after that the chain rule )
y´ = ( x ) ´· e^(-x/2) + ( e^(-x/2)´ · x) =
=
d/dx( f(x) · g(x) ) = f´( x ) g( x ) + g´( x ) f( x ) ( and after that the chain rule )
y´ = ( x ) ´· e^(-x/2) + ( e^(-x/2)´ · x) =
=
