Question

The function f : X → R is defined by f(x) = x³+ 1, where X = {-1, 0, 3, 9, 7}.

✓

Answer

f : X → R given by f(x) = x³ + 1
f(-1) = (-1)³ + 1 = -1 + 1 = 0
f(0) = (0)³ + 1 = 0 + 1 = 1
f(3) = (3)³ + 1 = 27 + 1 = 28
f(9) = (9)³ + 1 = 81 + 1 = 82
f(7) = (7)³ + 1 = 343 + 1 = 344
Set of ordered pairs are {(-1, 0), (0, 1), (3, 28), (9, 82), (7, 344)}
