Which of the following statements about the graph of the function \(f(x)=|x|\) is correct?

Answer and explanation

Correct answer: It is symmetric about the \(y\)-axis and has range \([0,\infty)\).

Since \(f(-x)=|-x|=|x|\), \(|x|\) is an even function, so its graph is symmetric about the \(y\)-axis. Also, \(|x|\ge0\), giving range \([0,\infty)\). It is not one straight line because the slope changes at \(x=0\). Exam tip: test evenness using \(f(-x)=f(x)\).
