how do i write this equation?

hello, how do i write this?

my code is

k = abs(x).*exp(-abs(x)) 

[Walter Roberson]

Your k (lowercase) is fine for that; now you just have to integrate that according to the methods of your assignment.

You can use 'int' function to perform integration as following:

syms x;
k = int(abs(x).*exp(-abs(x)),x,[-3,3]);

[Walter Roberson]

This Question was really the continuation of another Question, in which the assignment was to use a riemann sum to approximate the integral.
