Final answer:
The value of f^-1(0) - is the x-coordinate where the invertible function f intersects the x-axis; however, without the actual graph, the exact value cannot be determined.
Step-by-step explanation:
To find the value of f-1(0), we are looking for the x-value on the graph of the invertible function f for which the y-value is 0. Since we know the maximum y-value on the graph is m which occurs when x=0, we must look for the point where the graph crosses the x-axis to find f-1(0). Unfortunately, without the actual graph provided it's impossible to give a specific answer. However, if we assume the graph touches the x-axis at some point, the x-coordinate of this intersection point is f-1(0), because at that point f(x)=0.
If the function f(x) is declining and invertible, one must search for the point where the graph crosses the horizontal axis (y=0) to answer the question. Nonetheless, without the graph, we cannot determine the exact value. If possible, please provide the graph or more details about the function for a more accurate answer.
