1.g(t) = f(t) + f(-t)
2. g(t)= f(t/2)
can someone pls explain why these functions are time variant and non causal

Causal and time variant is a concept in science that refers to the relationship between cause and effect, and how it changes over time. In other words, it is the understanding that the cause of a certain phenomenon or event can vary depending on the time at which it occurs.
Causal and time variant is different from causal and time invariant in that the latter assumes that the relationship between cause and effect remains constant over time, while the former acknowledges that this relationship can change over time.
Some examples of causal and time variant phenomena include the stock market, weather patterns, and human behavior. In each of these cases, the cause of a certain outcome can change depending on the time at which it occurs.
Understanding causal and time variant relationships is important in science because it allows us to better predict and explain complex phenomena. By recognizing that cause and effect can change over time, we can develop more accurate models and make more informed decisions.
Scientists can account for causal and time variant relationships in their research by using longitudinal studies, which track changes over time, and by incorporating time as a variable in their analyses. They can also use statistical methods that account for time-varying factors.
