To get an idea, graph the function using an application such as Desmos. The range tells you what values of y the graph may be. Looking at the graph, we see that y can be a value of 3 or larger (look at the y-intercept, which is the vertical line, and find the lowest point in comparison to the vertical line if the graph has a minimum. If it has a maximum, do the opposite). [tex] \geqslant [/tex] Means greater than or equal to. Therefore, the answer is C, which means y is greater than or equal to 3.
