a. Perform four iterations, if possible, on each of the functions g defined in Exercise 1. Let p₀ = 1 and p_n+1 = g( p_n), for n = 0, 1, 2, 3.

b. Which function do you think gives the best approximation to the solution?

Reference: Excercise 1:

Use algebraic manipulation to showthat each of the following functions has a fixed point at p precisely when f ( p) = 0, where f (x) = x⁴ + 2x² − x − 3.
