To find the range of the function depicted in the graph, we need to identify the minimum and maximum $y$-values that the graph reaches.

Observing the graph:

1. The lowest point on the graph is at $y = -4$.
2. The graph continues upwards to positive infinity, as indicated by the arrow on the top part of the curve.

From this, we can conclude:

• The range starts at $-4$ and extends to infinity.

Thus, the correct answer is:

Option B: $[-4, \infty)$

Here are some related questions you might find helpful:

1. What does the range of a function represent in mathematical terms?
2. How would the range change if the graph had a different minimum point?
3. Can the range of a function include infinity in a closed interval?
4. What are some methods to determine the range of a function from its equation?
5. How does the range relate to the domain of a function?

Tip: Remember, the range represents all possible output values (y-values) of the function. Identifying extreme points on a graph is a quick way to determine it.
