Hosted by The Math Forum## Problem of the Week 1098## Name that Tune ... er ... Polynomial!Bob: Let's play "Name that Polynomial." I'm thinking of a polynomial p(x) with nonnegative integer coefficients. You need to guess what it is. Alice: Is it bigger than a breadbox and smaller than a house? Bob: Ha ha, very funny. If you give me any integer x then I will tell you the value of p(x). Alice: You're not even going to tell me the degree of the polynomial? Bob: Nope. Try to figure out p(x) using the fewest queries. What is the least number of queries Alice needs to determine the polynomial p(x)? (Her first two questions above don't count!)
