This question is attached.
Just in case you cannot see it, it asks to express the function f(x) in terms of the Heaviside function.
f(x)=x+1 when x<-1
3x when -1<x<1
2-x when x>1
I don't understand how to do this at all so please go easy on me. Baby steps .
For example, if the problem had been
for < 2 and for
I would have thought "on the left (x< 2) I have so I have to have that without any H. For x> 2, I want so , the formula wanted in the second interval with the formula from the first region subtracted off to cancel the that is no longer wanted.
In other words, .
