\( 27 f ( x ) = \left\{ \begin{array} { l l } { x ^ { 2 } } & { x \leq - 1 } \\ { 2 x + 3 } & { - 1 < x < 0 } \\ { 4 } & { x > 0 } \end{array} \right. \)

Quick Answer
La funzione \( f(x) \) è definita a tratti come segue:
- Per \( x \leq -1 \): \( f(x) = \dfrac{x^2}{27} \)
- Per \( -1 < x < 0 \): \( f(x) = \dfrac{2x + 3}{27} \)
- Per \( x > 0 \): \( f(x) = \dfrac{4}{27} \)
Questo significa che la funzione comporta una parabola per valori di \( x \) minori o uguali a -1, una retta lineare per valori compresi tra -1 e 0, e una linea orizzontale costante per valori di \( x \) maggiori di 0.
