Plsss help cause i just don’t understand

Domain: [-2, 4]

Range: [-2, 0]U[0, 4]

Step-by-step explanation:

Domain is the input of any x-value according to the graph. Since the domain only stretches from x = -2 to x = 4 (with no holes or asymptotes), our domain would be [-2, 4] (brackets because those values are included).

Range is the output of y-values from x-values according to the graph. Since our graph extends from only -2 to 4 on the y-axis, but we have a jump at x = 0, our range would be [-2, 0]U[0, 4] (We use the union to signal the jump discontinuity and the brackets because those values are included).
