Using the concepts of domain and range, it is found that:
- The domain of the relation is {-1, 2, 3, 4}.
- The range of the relation is {-1, 0, 2, 4}.
<h3>What are the domain and range of a relation?</h3>
- The domain of a function is the set that contains all possible input values. On a graph, it is given by the values of x.
- The range of a function is the set that contains all possible output values. On a graph, it is given by the values of y.
In this graph, the points represented are given by: {-1, 2}, {2,0}, {3,-1} and {4,4}. Hence:
- The domain of the relation is {-1, 2, 3, 4}.
- The range of the relation is {-1, 0, 2, 4}.

Answer:
C. 215.12 feet per second
Step-by-step explanation:
Sergei's car was clocked in a quarter mile race at 146.67 miles per hour.
How many feet per second is this to the nearest hundredth if there are 5280 feet in one mile?
From the above question
1 mile = 5280 feet
1 hour = 60 minutes
1 minutes = 60 seconds
1 hour = 60 × 60 seconds = 3600 seconds
We are to convert 146.67 miles per hour = feet per second
Hence:
146.67 miles /1 ft × 5280 feet/1 miles × 1 hr/3600 seconds
= 146.67 × 5280 feet/3600 seconds
= 774417.6 feet / 3600 seconds
= 215.116 feet per second.
Approximately = 215.12 feet per second

Answer:
y = -2(4) -3
Step-by-step explanation:
y = mx + b
m in the equation means <u>slope</u>
x in the equation means <u>x intercept</u>
b in the equation means <u>y intercept</u>
y = -2(4) -3

Answer:
157,476 people
Step-by-step explanation:
the formula :
P(x) = 86700. (1+ 0.089)^r
for r = 7
=> P(x) = 86700 × (1+ 0.089)^7
= 86700 × (1.089)^7
= 86700 × 1.8163
= 157,476 people
