Dear Saurabh Sharma, please use the panel for submitting a new question.
Let φ(x) = 1 4 + x − x 2 . For a given r ∈ R, consider the sequence {xn}, which is defined by x1 = r and xn+1 = φ(xn), n ∈ N. If the sequence converges, let r∞ be the limit. (a) For r = 0, prove that {xn} is bounded and monotonic. Find r∞ = β. (b) Find all r 6= 0 such that r∞ = β. (
