Answer

$b$ and $c$

Work Step by Step

The vertical line test states that a graph represents a function if any vertical line that is drawn through the graph only passes through one point in that graph. In graph $a$, vertical lines drawn through the graph would pass through more than one point (example: $x=0$). In graph $b$, vertical lines drawn through the graph would pass through only one point. In graph $c$, vertical lines drawn through the graph would pass through only one point. Therefore, only graphs $b$ and $c$ are functions.
