Question

Which description is represented by a discrete graph?

Answer 1

The answer is A: Kiley bought a platter for $19 and several matching bowls that were $8 each. What is the total cost before tax?  Just took the test.

Answer 2

Answer:

C.) Juan ate an egg with 78 calories and some cereal with 110 calories per serving for breakfast. What is the total amount of calories he consumed?

Step-by-step explanation:

A discrete graph is a series of scatter plot points. It means point on graph aren't continuous manner.

Option A) Kiley bought a platter for $19 and several matching bowl that were $8 each. If she bought x number of bowl her total cost would be

C(x)=19+8x . This is linear function and the graph of linear function is continuous.  

This is not discrete graph.

Option B) Temperature at 9:00 AM was 83°F and heating up average rate of 6°F per hour.

Temperature after t hours would be

T(t)=83+6t . This is linear function and the graph of linear function is continuous.  

This is not discrete graph.

Option C) Juan ate an egg with 78 calories and some cereal with 110 calories per serving for breakfast.

Total calories = 78 + 110 . Total calories not depend on any variable.

This is discrete graph.

Option D) a bottle contained 2,000 mL of liquid and is being poured at an average rate of 300 mL per second

W(t)=2000-300t , This is linear function and the graph of linear function is continuous.

This is not discrete graph.
