SAT Question 2b6c12eb: Nonlinear Functions answer and explanation with Desmos solution

An x-intercept of a graph is a point on the graph where it intersects the x-axis, or where the value of $y$ is $0$. The graph shown intersects the x-axis at the point $\left(6,0\right)$. Therefore, the x-coordinate of the x-intercept of the graph shown is $6$.
