Step-by-step Solution

Para representar los conjuntos en forma de intervalo y en la recta numérica, procederemos de la siguiente manera: ### a. \( \{x \in \mathbb{R} \mid -5 < x \leq -1\} \) **Forma de intervalo:** \[ (-5, -1] \] **Recta numérica:** ``` <----|----|----|----|----|----|----|----|----|----|----> -6 -5 -4 -3 -2 -1 0 1 2 3 (-----------------] ``` ### b. \( \{x \in \mathbb{R} \mid -4 \leq x < 1\} \) **Forma de intervalo:** \[ [-4, 1) \] **Recta numérica:** ``` <----|----|----|----|----|----|----|----|----|----|----> -6 -5 -4 -3 -2 -1 0 1 2 3 [-----------------) ``` ### c. \( \left\{x \in \mathbb{R} \left\lvert\, \frac{1}{2} 0 0.5 1 1.5 2 (-----------) ``` ### d. \( \left\{x \in \mathbb{R} \left\lvert\, 0 \leq x \leq \frac{4}{3}\right.\right\} \) **Forma de intervalo:** \[ \left[0, \frac{4}{3}\right] \] **Recta numérica:** ``` <----|----|----|----|----|----|----|----|----|----|----> 0 0.5 1 1.5 2 [-----------------] ``` Estas son las representaciones de los conjuntos en forma de intervalo y en la recta numérica.

Quick Answer

a. Intervalo: \((-5, -1]\), Recta: \((-5, -1]\) b. Intervalo: \([-4, 1)\), Recta: \([-4, 1)\) c. Intervalo: \(\left(\frac{1}{2}, \frac{3}{2}\right)\), Recta: \(\left(\frac{1}{2}, \frac{3}{2}\right)\) d. Intervalo: \(\left[0, \frac{4}{3}\right]\), Recta: \(\left[0, \frac{4}{3}\right]\)
