How is the initial value of a function represented in a a table and in a graph?

In a table, the initial value of a function is typically represented as the output corresponding to the input value of zero, often found in the first row of the table. In a graph, the initial value is shown as the y-coordinate of the point where the graph intersects the y-axis, which corresponds to the function's value when the input (x) is zero. This point serves as a starting point for understanding the behavior of the function.
