Consider the sequence A defined by An= n* - 3n+3 Find the product I1=1 A; : 1. N-1 A; = 1 2. -1A = 2 3. M-1A-0 Let consider a function f={(1.c),(2,a),(3,b); We define the domain X = {1, 2, 3) and the codomain Y = {a,b,c}. Is the function f one-to-one, onto or a bijection? 1. This function is not one-to-one 2. This function is not onto 3. This function is called a bijection. Let consider the sequence b, c This sequence is a subsequence of the sequence T, We define 1 Snss. Find the element of the sequence T.: 1. T. = {T, -a, T= a, T3 =b, To=e, Ts = d } 2. T. = {T, =b, T,=b, Tz =c, T4 =a, Ts = d) 3. T. = { T, =c, T, =b, Tz = a, T4=b, Ts Ed}
