Answer variants:

$(x^4 - 2x^2)^2 - 1$

$x^4 - 2x^2$

$\{y | y = (2x + 1)^2, x \in \mathbb{N}\}$

$\{y | y = (2x + 1)^3, x \in \mathbb{N}\}$

$x^4 - 2x$

$\{y | y = 2x + 1, x \in \mathbb{N}\}$

$\{y | y = 2x^2 + 1, x \in \mathbb{N}\}$

$x^4 - 2x^2 - 1$

Let

$A$ ,

$B$ ,

$C$

$\subseteq$

$\mathbb{N}$ and a function

$f: A \rightarrow B$ be defined by

$f(x) = 2x + 1$ and

$g: B \rightarrow C$ be defined by

$g(x) = x^2$ . Find the range of

$f \circ g$ and

$g \circ f$ .

The range of

$f \circ g$

$=$

The range of

$g \circ f$

$=$
