Answer:
![f(x)\geq -2](https://img.qammunity.org/2021/formulas/mathematics/high-school/fuhchfncblmrbqodw3jra0v2rbzzs0h82f.png)
Explanation:
Range corresponds to the values of y on the y-axis. If we see the graph the minimum value of the y-coordinate is -2 and then it tends to increase from it. We do not know till where the y values will increase in the figure it shows 6 but it's still actually increasing we keep on tracing the graph but the minimum value will always remain the same which is -2 . So we can say that the range of the function is
![f(x)\geq -2\\](https://img.qammunity.org/2021/formulas/mathematics/high-school/khvrg3wrdwd8jw02ukbymw69jcbd4qo51b.png)
Where f(x) is the function and since the values of y on the y-axis increase from -2 we can say that the function has the range of values greater than or equal to -2
