No

Work Step by Step

THEORY: By definition of a function, for every value of $x$, there must be only one $y$. This means that any vertical line intersects the graph in at most one point. . IN THIS QUESTION: In this problem, the table does not define $y$ as a function of $x$ because for the same value $x=150$, we have two different values of $y$: $7$ and $8$. It means the vertical line test failed. So the table does not define $y$ as a function of $x$.
