Which description best matches the graph of \(f(x)=|x|\)?

Correct answer: A V-shaped graph with vertex at \((0,0)\) and symmetry about the y-axis

For \(f(x)=|x|\), the value is \(|x|\ge 0\). When \(x\ge0\), \(|x|=x\) (a line with slope \(1\)); when \(x<0\), \(|x|=-x\) (a line with slope \(-1\)). These two rays meet at \(x=0\), giving a V-shape with vertex at \((0,0)\). The function depends only on \(x\) through \(|x|\), so it is symmetric about the y-axis.
