Consider the signal x(\cdot) defined by the following graph:

The signal is zero outside the range -2\lt t\lt 2.

Part 1.

The following plot shows y_1(\cdot), a signal that is derived from x(\cdot).

Determine an expression for y_1(t) in terms of x(\cdot). Enter your answer as a Python expression:

y_1(t) =~

Part 2.

The following plot shows y_2(\cdot), a signal that is derived from x(\cdot).

Determine an expression for y_2(t) in terms of x(\cdot). Enter your answer as a Python expression:

y_2(t) =~
