Answer:

<u><em>What is the importance of polynomial functions?</em></u>

<u><em> </em></u>Polynomials are an important part of the "language" of mathematics and algebra.

<u><em>How these real-life applications improve or contribute to the value of life?</em></u>

Since polynomials are used to describe curves of various types, people use them in the real world to graph curves. Combinations of polynomial functions are sometimes used in economics to do cost analyses, for example. Engineers use polynomials to graph the curves of roller coasters and bridges.
