The range is all of the y values.
The domain of all quadratics is all real numbers, but the range of y=x^2 is y≥0. This is because quadratic functions graph to form a parabola, which, when the a value is positive, opens upward. The lowest y value when graphed is 0 and all other values are more than that.
