What is Time Invariance?
Time Invariance describes a property of a system such that the input of signal shifted k units in time equals it's respective output shifted k units in time.
An example of time invariance
Suppose a system is modeled mathematically as: $ \ f(x)= 5x <sup> 2 </sup> + 6 \ln(x) + 9 $
