At which point does the graph of \(f(x)=x^2\) touch the x-axis?

Answer and explanation

Correct answer: (0,0)

A point on the x-axis has y-coordinate 0. Thus, \(x^2=0\), giving \(x=0\) and the point \((0,0)\). The parabola \(y=x^2\) has its vertex at \((0,0)\), where it touches the x-axis. The points \((1,0)\) and \((-1,0)\) are incorrect because the function values there are 1, not 0. Exam tip: Since \(x^2\) is always non-negative, the graph does not cross the x-axis.
