Question

Is the system causal and does it have memory?

equation below.

Answer 1

\[y(t) = \int\limits_{-\infty}^{2t} x(\tau)d \tau \]

Answer 2

I think its not causal because for \[y(t _{0}) \] where \[t_{0} > 0 \] it depends on x(t) for
\[-\infty < 2t \] but not less than or equal to \[t_0\]

Answer 3

but im unsure of if it has memory
