In the question "What is the initial value of the function represented by the graph?" The initial value of a function is the value of the function when x = 0, i.e. f(0). For the graphof a function, the initial value is the point where the graph crosses the y-axis. For the given graph, the graph crossed the y-axis at the point (0, 4). Therefore, the initial value of the function represented by the graph is 4.
