Question

plz answer the (b) question with explaination!!!!!!!!!!!!!!urgent!!!!!!!!!!!!!!!!!!!!!!p.s if you dont know dont answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!​

Answer 1

Answer:

= (1/2) (integral) ex dx - (1/2) (integral) ex dx

solve left equation

= (1/2) ex - (1/2) (integral) ex dx

set

u = - x

then we find

du = - dx

substitute du= - dx, u= - x

= (1/2) ex + (1/2) (integral) - ex dx

= (1/2) ex + (1/2) (integral) eu du

solve the right integral

= (1/2) ex + (1/2) eu + C

substitute back u= - x

= (1/2) ex + (1/2) ex + C

=

ex + ex

2

+ C

which by definition

Step-by-step explanation:

and the answer is option B
