Question

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

✓

Answer

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