Question

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

A all real numbers less than or equal to 8

B all positive real numbers

C Real numbers from 0 to 8

D all integers less than or equal to 8​

Answer 1

C. Real numbers from 0 to 8

Explanation:

Given:

The graph above

Required

Determine the domain of the graph

The first step is to get the range of the depth of the pond

[this is plotted along the y axis]

The highest plot on the y axis is 95 and the least is 0

The next is to determine the corresponding time for the value listed above

When y = 95, x = 0

When y = 0, x = 8

The domain is x: 0 to 8

From the list of given options, option C correctly answers the question.
