Find the composition of functions — task. Maths TNSB Mentoring, Class 10.

Find \(f \circ g\) and \(g \circ f\) when \(f(x) = 2x + 1\) and \(g(x) = x^2 - 2\).

\(f \circ g\) \(=\)

$4 x^{2} + 4 x - 1$
$4 x^{2} + 4 x + 1$
$2 x^{2} + 3$
$2 x^{2} - 3$

\(g \circ f\) \(=\)

$4 x^{2} + 4 x + 1$
$4 x^{2} + 4 x - 1$
$2 x^{2} + 3$
$2 x^{2} - 3$
