Question

The water was pumped out of a backyard pond. What is the domain of this graph?

Answer 1

In case of graph, for domain we consider all the x values.
Domain is all input values for which we get a real output or all possible x values for which we get real y values.
here from the graph we can see the possible x values are all real numbers from 0 to 6
So option B is correct.
