Answer:
Explanation:
The range is [-4, ∞)
Using a graphing calculator (desmos) we can obtain a graph of the following function.
Explanation:
In the graph, we can see that there is a point a -4 and nothing lower, making it our minimum y-value. However, we cannot see an ending for the function; therefore, it is indeterminable and thus, infinity. As for notation. we use the solid bracket because we know the definite point, though because infinity is not definite we just use a parentheses to enclose it.
