Question

The chemical X is added to a solution to change the growth of the microbes. Which of the following data is plotted in the given graph ?
What is the nature of the function?

• A.
  It is an increasing function.
• B.
  It is an increasing function.
• C.
  It is an increasing function.
• D.
  It is a decreasing function.

Answer 1

The correct option is A

It is an increasing function.
From the given graph, the approximate population in 1 hour is 60 millions.

Also, the approximate population in 2 hours is 180, and at 4 hours is 270 millions.

Hence, the data plotted on the given graph is



As the time increases, the pupulation also increases.

Hence, the function is an increasing function.
