Answer:
B. 40 ≤ e ≤ 100
Explanation:
In a function, the domain values are the independent variables, and are always plotted on the x-axis, while the range values the dependent variables, which are always plotted on the y-axis on a graph.
From the graph given, it shows that f is a function of e. Which is,
.
Therefore, the range of the function would be: B. 40 ≤ e ≤ 100
