In which situations would you NOT use a polynomial function to model a real-world phenomenon? Question 23Answera.Predicting population growth over time. b.Calculating the distance travelled by a car with time.c.Estimating the gas levels during the dive with respect to the depth of the ocean.d.In the process of vaccines development.

Polynomial functions are not ideal for modeling certain real-world phenomena due to their characteristics. Here are the situations from your list where you would NOT use a polynomial function:

a. Predicting population growth over time: Polynomial functions are not the best choice for this because population growth is often exponential rather than polynomial. An exponential function would be a better fit as it can handle the rapid increase that is often seen in population growth.

d. In the process of vaccines development: The development of vaccines involves a lot of variables and uncertainties, including biological reactions that are not easily quantifiable or predictable. Polynomial functions, which are deterministic, may not be suitable for such complex and uncertain scenarios. Instead, stochastic models or models based on differential equations might be used.
