welshfella · Answer

First thing  since the x axis is in units of days make the domain 21 days.

welshfella · Answer

Yes your answer to b is correct.

freemap · Answer

Are you looking at question #3?

welshfella · Answer

oh sorry  i was looking at question 1
1(c)  is incorrect though the number in parentheses after B refers to the number of days

so correct is B(12) = 0

freemap · Answer

oh thanks so much for telling me

freemap · Answer

that it was incorrect

freemap · Answer

Were they less than $100 on a for number 3

welshfella · Answer

OK 
Question 3
(a)  On 16th day she had zero in her account and added $100
Note the slope of that graph for the period of 1 day. After that the graph still had a positive straight slope but it was not so steep . This shows that she added a constant amount each day  but was it more than $100 or lot?

welshfella · Answer

If it was $100 each day then the graph would keep the same slope.

freemap · Answer

ok so if shes adding $100 everyday, then yes it would be more than $100. Right? because shes keeping the same slope of a $100 ?

freemap · Answer

@welshfella

freemap · Answer

wait but keeping the same slope wouldn't change right, so it would be less than a $100

welshfella · Answer

No after the 16th day she is not keeping the same slope
