I need this answered fast

a= domain = 3x range = 21-3 = 18

b= $200 As 0(B) = Point of origin balance = midway to $400

= 0 < 200 > 400 = midway 200.

c=function notation =  3x -3x + 6 = 21  we change the 3x to cancel out any balance.

d= 4th segment shows day 12 to day 15 across the x axis.

ok we see and count after reading this it has 21 days in total approx and 12th day it shows the function went to 12 days.

We can write F(x) = 12x+6 to equal the change in value then we need to distribute 12 x = 6

Which is the same as 9 days money = 6 days money

As 3 days was made reference to day 12- day 15 where she had zero in account. We can minus - 3 also to represent her last savings before adding the balance of 6.

ok no interest the maximum was $400 the zero y intercept (0.0)= $200

This makes everything so easy now.

We count 21 days =  21 this is what we will end with

Let 4 be x

4x -3 + 6  

We count 5 change $  values 0, 1 , 2, 3, 4 on the graph and also 4 in repeat which makes the 400.

or could mean she started with 400 and the rest is interest. Now we know this we cna start writing a domain and i will keep this open and edit and try work this out for you.

Step-by-step explanation:

The last step for question one is converting 12 into 12

This means 4x = 3 so we change it to

3x -3 +6 = 21

Then you now can recognize and accept x = 4

(a)

Domain: 0 to 21

Range: 0 to 400

(b)

B(0) = 200.

(c)

B(12) = 0

(d)

Segment 4. The value of B(d) in Segment 4 is 0.

Step-by-step explanation:

(a) The domain is the number of days. The range is the amount of money which is the number of dollars. The account was open for 3 weeks, and the graph shows the entire 3 weeks. 3 weeks = 21 days; the highest amount of money was $400.

Domain: 0 to 21

Range: 0 to 400

(b) B(0) is very close to half of the maximum value of B(d). Since the maximum value of B(d) = 400, B(0) = 200. B(0) means the value of the function at time 0. The account was opened with an initial deposit at time = 0. B(0) is the value of the account at time = 0 which is the initial deposit made to open the account.

(c)

B(12) = 0

(d)

There are 6 segments:

Segment 1: B(d) goes from $200 to $400.

Segment 2: B(d) remains at $400.

Segment 3: B(d) goes from $400 to $0.

Segment 4: B(D) remains at $0.

Segment 5: B(d) goes from $0 to $100.

Segment 6: B(d) goes from $100 to $300.

In Segment 4, the value of B(d) is 0, so Segment 4 represents days 12 through 15.

i dont know if you cant find a way its best to actually add all of them start from 105 tho
