Austin is surfing the net and comes across Electronics-R-Us. He decides to purchase a few DVDs. The equation c = 19.99n + 4.99 can be used to find the total cost, c, of purchasing n DVDs from this online store. What is the dependent quantity of this relationship? F. the number of DVDs (n)
G. $4.99
H. $19.99
J. the total cost (c)

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

whole number data type

step-by-step explanation:

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type

h is the x-coordinate of the vertex

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
