Final answer:
The limit of the function f(x) is 10 for any x within the interval 0 to 20, as the graph is a horizontal line at f(x) = 10. Limits can only be evaluated within the domain of the function, which in this case is from 0 to 20 inclusive.
Step-by-step explanation:
Finding Limits Using a Graph
To find the limit of the function f(x) as described, we can use the information provided in the graph.
Since the graph of f(x) is a horizontal line at f(x) = 10 for 0 ≤ x ≤ 20, the limit of f(x) at any value of x within that interval is simply 10.
This is because a horizontal line indicates that the function value does not change as x varies within the given range.
In case the question refers to a limit as x approaches a certain value, as long as the value is within the interval 0 ≤ x ≤ 20, the limit remains 10.
It is important to note that limits can only be discussed at points within the domain of the function.
When the graph is not continuous at the point or if the point lies outside the defined range, then one can say the limit does not exist.
Since the problem states that the function is restricted to 0 ≤ x ≤ 20, and given the graph is a horizontal line, we can confidently say that the limit of f(x) for any x in this interval is 10.
If the question is about a limit at an x-value outside this interval, then we would consider if the function were to be extended beyond the interval or not before determining the limit.
