Answer:
30
Step-by-step explanation:
The factors of 120 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, <u>30</u>, 40, 60, 120
The factors of 150 are: 1, 2, 3, 5, 6, 10, 15, 25, <u>30</u>, 50, 75, 150
Then the greatest common factor is 30.
It is not a function because both (2,2) and (2,-2) have the same x-coordinate.
To be a function for the same x value there should NOT be two different y values.
So, in (2, 2) and (2,-2)
For the same x value 2, there are two different y values 2, -2.
So, this is not a function.
its C
I believe the answer ur looking for is 3 (D)
