Suppose S = {0, 1, 2, 3, 4, 5, 6, 7) and that the function f:S → S is given by: f(x) = 4x2 + 5x + 1 (mod 8). Let T = {3,7}. Recall that the Numbas syntax for the set {a,b,c} is set(a,b,c). a) What is f(T)? Expected answer: set (4,0) {4,0} set (4,0) (4,0) Your answer is numerically correct. You were awarded 1 mark.
