Answer:
The domain is {1,2,3,4,5}
The range is {150,135,120,105,90}
Step-by-step explanation:
Domain is the set of x-values (x axis) and Range is the set of y-values (y axis).
Now if you look at the relation (points given), you can see the 5 points corresponds to 1,2,3,4, adn 5 in the x axis (minutes). So this is the domain - 1,2,3,4,5.
If we look at the y-axis (Heart Rate) , the values corresponding to 1,2,3,4,and 5 are 150, 135, 120, 105, and 90. These are the range.
Hence the last choice is the correct answer.
