Which standard function has a parabola as its graph, with vertex at the origin and symmetry about the y-axis?

Answer and explanation

Correct answer: \(y=x^2\)

The graph of \(y=x^2\) is an upward-opening parabola with vertex \((0,0)\), and its two sides are symmetric about the y-axis. Although \(y=|x|\) is also symmetric, it is V-shaped rather than parabolic. Exam tip: look for the quadratic power 2 to identify a parabola.
