  This paper proves a conjecture generated by the artificial intelligence
conjecturing program called \emph{TxGraffiti}. More specifically, we show that
if $G$ is a connected, cubic, and claw-free graph, then $Z(G) \le \gamma(G) +
2$, where $Z(G)$ and $\gamma(G)$ denote the zero forcing number and the
domination number of $G$, respectively. Furthermore, we provide a complete
characterization of graphs that achieve this bound. Notably, this bound
improves the known upper bounds for the zero forcing number of connected,
cubic, and claw-free graphs.
