What is the quadratic parent function?

The quadratic parent function is represented by the equation ( f(x) = x^2 ). It is a basic polynomial function that forms a parabolic graph opening upwards, with its vertex at the origin (0, 0). The function is symmetrical about the y-axis and has a minimum value of 0 at the vertex. The shape of the parabola is defined by its standard form, which can be transformed through vertical and horizontal shifts, stretches, or reflections.
