Which description is represented by a discrete graph? a. kiley bought a platter for $19 and several matching bowls that were $8 each. what is the total cost before tax? b. the temperature at 9 a. m. was 83° f and is heating up at an average rate of 6°f per hour. what is the temperature x hours later? 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? d. a bottle contained 2,000 ml of liquid and is being poured out at an average rate of 300 ml per second. how much liquid is left in the bottle after x seconds?

Answer : A and D can be  represented by a discrete graph.

A discrete graph is a series of countable unconnected points with

domain→ a set of input values including all numbers in an interval.

A. This description can be represented by a discrete graph because we can count the number of bowls Kiley bought.  ∴ it's not continuous.

B. This description cannot be represented by a discrete graph because it will gently get hotter with time. The temperature can be in decimal form.∴This description is said to be continuous not discrete.

C. This description can be represented by a discrete graph because there Juan ate 78 calories and 110 calories,∴ the total amount of calories he consumed= 188 calories. After that there is no other input ,so it is countable and is discrete.

D. This description cannot be represented by a discrete graph ∵this is continuous as with respect to time liquid is being poured out so we cannot count liquid ∴ this is not discrete.
