11. Like we have worked to understand families of functions that involve parameters such as p(t) = a cos(k(t - b)) + cand F(t) = a + be *t, we are often interested in polynomials that involve one or more parameters and understanding how those parameters affect the function's behavior. For example, let a > 0 be a positive constant, and consider p(x) = 13 - alr. a. What is the degree of p? b. What is the long-term behavior of p? State your responses using limit notation. c. In terms of the constant a, what are the zeros of p? d. Construct a carefully labeled sign chart for p. e. How does changing the value of a affect the graph of p
