Identify the mapping diagram that represents the relation and determine whether the relation is a function. {(-1, -9),(0, -9), (4, -9), (5, -9)} (1 point)
The mapping diagram for the relation {(-1, -9),(0, -9), (4, -9), (5, -9)} would look like:
-1 -> -9
0 -> -9
4 -> -9
5 -> -9
Since each input has only one corresponding output, the relation is a function.
-1 -> -9
0 -> -9
4 -> -9
5 -> -9

Bean sprouts grow very quickly. A bean sprout has grown to a height of 5 millimetrs. Tomorrow it will be 14 millimeters tall, the next day it will be 23 millimeters tall, and on the next day it will be 32 millimeters tall.
Part 1) Write a rule to represent the height of the bean sprout as an arithmetic sequence.
(1 point)
Responses
A(n) = 5 + (n - 1) 9
A(n) = 5 + (n - 1) 9
A(n) = 14 + (n - 1)9
A(n) = 14 + (n - 1)9
A(n) = 5 - (n - 1)9
A(n) = 5 - (n - 1)9
A(n) = 9n
A(n) = 9n
A(n) = 9 + (n + 1)5
A(n) = 9 + (n + 1)5

A violinist charges $75 for a visit and an additional $25 for each hour she performs.
Part 1) What is the function rule if C represents the total cost of the visit and h represents the number of hours?
(1 point)
Responses
C = 75h + 25
C = 75h + 25
C = 75h - 25
C = 75h - 25
C = 25h - 75
C = 25h - 75
h = 75C - 25
h = 75C - 25
C = 25h + 75
C = 25h + 75
h = 75C + 25
h = 75C + 25

Question 2
Part 2) If the violist will only visit a maximum of 6 hours, what is a reasonable graph of the function rule?(1 point)
Responses
Part 1) The function rule for the total cost of the visit is C = 75h + 25.
Part 2) A reasonable graph of the function rule would show a linear relationship, with the x-axis representing the number of hours (h) and the y-axis representing the total cost (C). The graph would start at a y-intercept of 25 and slope upwards. It would have a maximum of 6 hours on the x-axis.
