SAT Question c10ad793: Linear Functions answer and explanation with Desmos solution

Choice A is correct. The x-intercept of a graph is the point where the graph intersects the x-axis. The graph of function $f$, where $y=f\left(x\right)$, intersects the x-axis at $\left(-12,0\right)$. Therefore, the x-intercept of the graph of $f$ is $\left(-12,0\right)$.
