Ya'll . the water was pumped out of a backyard pond, what is the domain of this

A. Real numbers from 0 to 8.

Step-by-step explanation:

Since, the given graph represents the depth of water pumped out of the backyard pound,

So, time ( in minutes ) must show the input value and depth ( in inches ) must show the output value,

Also, by the given graph,

Time is defined from 0 to 8 minutes,

Thus, the possible input values of the function of the graph are all the real number between 0 to 8,

Now, we know that the set of all possible input values is called domain of the function,

Hence, the domain of the given graph is,

Real numbers from 0 to 8.

Option 'A' is correct.
