Question

The cost of food items bought from a shop is shown below.

Determine the nature of graph with a valid reason.

• A. It is a discrete graph because they are not continuous.
• B. It is a discrete graphs because they have only certain range of values.
• C. It is a continuous graphs because they are not continous.
• D. It is a continuous graphs because they have only certain range of values.

Answer 1

The correct option is B It is a discrete graphs because they have only certain range of values.

Discrete graphs show values along a number line at precise point. They might or might not indicate a trend or a direction. These graphs do not include any values that are not whole numbers.Following observation can be made through this graph:
$\Rightarrow$There is no intermediate values between the points because 1.5 food items makes no sense. Hence it is a discrete graph.
$\Rightarrow$This graph have only certain range of values.
Hence, Option(b) is correct.
