If the function is defined for only a few input values then the graph of the function is only a few points where the x coordinate of each point is an input value and the y coordinate of each point is the corresponding output value. If an algebraic equation de. The graph shown here has 2 curves and one straight line.
In the above situation the graph will not represent a function.
Use the vertical line test to determine whether the. We can have better understanding on vertical line test for functions through the following examples. It is a function. Graphs help us understand different aspects of the function which would be difficult to understand by just looking at the function itself.
