$latex \mathbf{Question:} \text{ Let } f_n \to f \text{ pointwise at every point in the interval } [a,b] .\\
\text{ And } f_n \text{ is continuous }. \text{ Which of the is/are true ?} \\ \\
1. \text{ If each } f_n \text{ is increasing on } [a,b], \text{ then so is } f\\
2. \text{ If each } f_n \text{ is bounded on }[a,b], \text{ then so is }f\\
3. \text{ If each } f_n \text { is everywhere discontinuous on } [a,b], \text { then so is } f\\
4. \text{ If each } f_n \text { is constant on } [a,b], \text{ then so is } f
