Answer:
(1, 1)
Step-by-step explanation:
We need to evaluate the given expression for each of the x-values and check if the y-value agrees with the y-value given in the pairs:
1) First point (-1,3): use x=-1 and check if y results in "3":

we obtained y=-7, so the point (-1,3) is Not on the graph of the function
2) Second point (0,2): use x=0 and check if y results in "2":

we obtained y=-2, so the point (0,2) is Not on the graph of the function
3) Third point (2,-2): use x=2 and check if y results in "-2":

we obtained y=2 (and not -2), so the point (2,-2) is Not on the graph of the function
4) Fourth point (1,1): use x=1 and check if y results in "1":

we obtained y=1 (the same y as in the given coordinate pair), so the point (1,1) IS on the graph of the function
Answer:
Step-by-step explanation:
I can only do the first one, and then only by brute force. If both numbers can be the same, then David would write 143143
143 * 143 = 20449
7 * 20449 = 143*143. It is the only answer that came up from 100 to 999.
If I get the second one, I'll put it in the comments. But I can only do it by brute force as well, if I can do it at all.
0,8 is the answer because 5*6+1/6=5,2 and 6-5,2=0,8
The answer is b because it goes up down then up
