Question

Write a function for the situation. Is the graph continuous or discrete? A movie store sells DVDs for $11 each. What is the cost, C, of n DVDs?
A. C = 11 + n; discrete
B. C = 11n; continuous
C. C = 11 + n; continuous
D. C = 11n; discrete

Answer 1

A discrete set is {1, 2, 3}, so a discrete set is countable
A continuous set is {1-3} a continuous set is not countable

Does the store sell parts of the DVDs or do they sell single or multiple dvds

Answer 2

o ok thanks man i got it now

Answer 3

when you have a discrete number of things these things are easily separable and distinct

Another example having 2 apples is discrete because we are only counting the apples as wholes

Having making a cut between 2mm and 4mm, there are infinite amount of lengths between 2mm and 4mm to cut the material

Answer 4

so it would b B rite

Answer 5

For the function think about it logically what function matches the data,

you sell one dvd you get 11 dollars
you sell two dvds you get 22 dollars
etc.

Answer 6

read what I wrote

Answer 7

I dont think you are understanding the difference between discrete and continuous

Answer 8

hey dont get mad at me seriosly this is the first time i c this ?

Answer 9

I'm not mad

Answer 10

I'm just being honest with you, maybe my explanation isnt good enough.

Answer 11

so a continuous set would include all values between 1 and 2, there are infinite amount of values between 1 and 2

a discrete set,

would have only elements 1, 2, 3. so it can be said to have 3 discrete elements

Answer 12

does this help?

notice that you could pick any number between 1 and 2 for the continuous set, so 1.44444, 1.88888888888, 1.234234234234 would all be in the continuous set

whereas with the discrete set we only have 1, 2, 3

Answer 13

if you graphed a continuous function it would look like this,



If you graphed a discrete function it would look lie this
