Which set of ordered pairs represents a function? {(2, –2), (1, 5), (–2, 2), (1, –3), (8, –1)} {(3, –1), (7, 1), (–6, –1), (9, 1

A function can't have x repeating any of the same number twice for example the first one (2, -2), (1, 5), (-2, 2), (1,-3), (8,-1) you have two 1's (1,5) and (1,-3) the x is the first number. Now a function can have the same y value. So your answer is (3, -1), (7,1), (-6,-1), (9,1), and (2,-1) you have to have all different x values in order for it to be a function. Hope that helps.
Answer:
i think it would be x two+ y two + six x + four y+ ten= one is that one the answers if so i hope this helps if not just give me the answers and i will try to help you as much as i can thanks
Step-by-step explanation:
The domain is all real numbers
The range is [4,infinity)
The end behavior is
As x—-> +infinity, f(x)—->+infinity
And as x——>-infinity, f(x)——>+infinity
Hope this helps!
Given:
The temperature on a mountain peak was 7°F at 6:00 p.m.
By 8:00 p.m., the temperature had dropped to 0°F.
To find:
The temperature at 11:00 p.m. if the temperature continued to drop at about the same rate.
Solution:
Time between 6:00 p.m. to 8:00 p.m. is 2 hours.
Change in temperature in 2 hours is -7°F.
Change in temperature in 1 hours is 
F.
Time between 8:00 p.m. to 11:00 p.m. is 3 hours.
Change in temperature in 3 hours is 
F, i.e., 
F.
Now, the temperature at 11:00 p.m is:
Therefore, the temperature at 11:00 p.m. is -10.5°F.
Note: All options are incorrect.
