1. Yes, the range $[0, \infty)$ means the minimum value of $y$ is 0 and there is no maximum value. 2. The minimum value 0 occurs at $x=0$ where $y=x^2=0^2=0$. 3. The maximum value is not bounded because as $x$ becomes very large (positive or negative), $y=x^2$ grows without limit. 4. So, $y$ can be any number starting from 0 and going up to infinitely large values. 5. In simple terms, $y$ is always at least 0 and can be as big as you want.
