which is the graph of the parent function f(x) = x^2

The graph of the parent quadratic function is the bottom graph.
The parent quadratic function is:
f(x) = x^2
The graph of this is known as a parabola, this is a curve with an axis of symmetry at line x = 0 (or just the y-axis)
With that in mind, the only option that shows a parabola is the bottom option (Which shows a parabola that passes through (0, 0) with both arms opening upwards).
