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 = 11n; continuous

B. C = 11 + n; discrete

C. C = 11 + n; continuous

D. C = 11n; discrete

Answer 1

1 DVD = 11$
so 'n' DVD's = 11n $
so the function is C+11n.
got thus ?

Answer 2

kinda, not too sure exactly

Answer 3

typo:C=11n.
now since the number of DVD's cannot be a fraction or cannot take any real values, but can only take discrete integer values like 1,2,3,4,....so it would be discrete.
