Final answer:
The value of the limit for the function f(x) when 0 ≤ x ≤ 20 is the same as the value of f(x) at any point within the interval, which is a constant.
Step-by-step explanation:
The value of the limit for the function f(x) when 0 ≤ x ≤ 20 can be determined since the graph of f(x) is a horizontal line between x = 0 and x = 20. Since the graph is a horizontal line, the value of the function f(x) is constant throughout this interval.
The value of f(x) can be found by evaluating the function at any value of x within the interval. For example, if we choose x = 10, the value of f(x) would be the same as the value of f at any other value of x within the interval, which is the slope of the line.
Therefore, the value of the limit for the function f(x) when 0 ≤ x ≤ 20 is the same as the value of f(x) at any point within the interval, which is a constant.
