The set of ordered pairs {(1,19), (2,23), (3,23), (4,29), (5,31)} represents the number of tickets sold for a fundraiser. The x-coordinates
represent the day and the y-coordinates represent the number of tickets
sold on that day.
a) Which mapping diagram represents the relation?

D. represents the relation.

D

Step-by-step explanation:

1) remember that x indicates the independent variable, while y the dependent variable

2) remember that the first diagram represents the values of x, while the second the values of y

the given growth  function for the length of the fish (cm) is

f(m) = 5(1.07)m = 5.35m

where 

m = months

at the end of the study, the length is 9.19 cm. the  time for conducting the study is determined as

5.35m = 9.19

m = 1.7178 months

part a.

the study was performed over a time period  of about 1.72 months. therefore  the domain for  plotting the function is 0 < = m < = 1.72.

note:

if growth  continues at this rate for up to m months, then the domain would be 0< =m< =m.

part b.

the growth function is a linear function.

when m=0, f=0.

therefore the initial growth is zero, which represents the y-intercept.

part c.

assume that the growth function is valid for 0< =m< =9.

the average rate of change of the function is the slope of the linear function, which is 5.35 cm/month.
