Homework Statement
Hi guys, so I'm struggling with understanding the heaviside function clearly. In particular, I am struggling to understand how changing f(t) to f(t-3) ''shifts'' everything to the right.
Homework Equations
Say we take the following heaviside function
f(t-3) = 7 for t >= 3
f(t-3) = 0 for t < 0
We get a graph that loops something like this:

The Attempt at a Solution
However, this doesn't make much intuitive sense to me. Say we are to plug in the value of t=3, then we should get at t=3, the value of f(0), but there has not been anything told to us about how the function behaves at f(0). Only that for values t>3, the value will be 7. So I don't really understand how this function is working.
Thanks for your time.
