Question

Let x(t) be a signal with x(t) = 0 for t < 3. Determine the values of t for which x(1 - t) is guaranteed to be zero?

Answer 1

Substituting x(t) = 0 into x(1 - t) gives 0(1 - t) = 0, which is satisfied for all values of t.

Step-by-step explanation:

To determine the values of t for which x(1 - t) is guaranteed to be zero, we need to substitute x(t) = 0 into the equation x(1 - t) and solve for t.

Substituting x(t) = 0 into x(1 - t) gives 0(1 - t) = 0. This equation is satisfied for all values of t, since multiplying anything by zero gives zero.

Therefore, x(1 - t) is guaranteed to be zero for all values of t.
