Question

Mellissa plotted the graph of a function. The function contains the points (2, 4) and (3, 6). The domain of the function is all whole numbers.

Mr. Wilson reviewed her work and said that the graph is incorrect. Explain why this graph is incorrect.

Draw a correct graph.

Answer 1

Because in that graph, the domain isn't all the whole numbers, it's all real numbers above 0. The graph in my pic would be the correct graph, because it would also contain negative numbers, and it's only the whole numbers.
