Answer:
36
Step-by-step explanation:
Work out the terms inside the parenthesis from x = 2 to x = 5. Hint: there will be 4 terms.
x = 2 ---> 0
x = 3 ---> 1
x = 4 ---> 2
x = 5 ---> 3
The sigma symbol means that you have to add them all up so the sum is 6. Therefore,
(6)^2 = 36
The independent variable is 12$ per hour since it is a rate of change and the dependent variable is the amount of money earned, since it is dependent on time(hours) worked. The domain is set of possible x values, in this case your domain is [0,40]. Then range is set of possible y values, which is amount earned, which is between 0 and 480. Meaning that your range is [0,480]
