Give the domain and range of each relation. Tell whether the relation defines a function a. {(13,12), (8, -3), (15,14), (5,17)}

b. {(3,21), (5, -11), (15,20), (3,4)}

c. {(9, -11), (5, -8), (21,1), (7, -4)}

d. {(19, -7), (10, -3), (1,7), (19,17)}

e. {(7,12), (11, 5), (14,12), (6, -1)}

answer: options?

step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
