Final answer:
The absolute maximum value of the function is determined by the shape of its graph: if it is a horizontal line at f(x) = 20, then the absolute maximum is 20; if it's a declining curve starting at f(x) = 0.25 when x = 0, then the absolute maximum is 0.25, known as m.
Step-by-step explanation:
The question pertains to finding the absolute maximum value of the function f(x) based on its graph within the domain 0 ≤ x ≤ 20.If the graph of f(x) is a horizontal line at f(x) = 20, then the absolute maximum is simply f(x) = 20 as the function does not attain any higher value within the given domain.
However, if the function represents a declining curve, the absolute maximum would be at the point where x = 0, which is given as f(x) = 0.25.
This value, f(x) = 0.25, is referred to as m, and it is the highest point on the y-axis for this curve.
