Homework Statement
Is the following input/output (x is input, y is output) system linear, time invariant, causal, and memoryless? Answer yes or no for each one.
Homework Equations
[tex]y(t)=2x(t)+3[/tex]
The Attempt at a Solution
My instinct tells me it's linear, but for some reason I have trouble showing it mathematically.It is linear if when you add scaled values of the input x(t), it equals the sum of the same scaled outputs. But it doesn't work out to be linear if I go by that definition
