Answer:
1. not a function.
2. is a function.
3. is a function.
4. not a function.
5. is a function.
6. not a function.
7. not a function.
8. is a function.
9. not a function.
10. is a function.
11. not a function.
12. not a function.
Step-by-step explanation:
1. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.
2. is a function because each input only goes to one output.
3. is a function because each input only goes to one output.
4. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It does not pass the vertical line test.
5. is a function because each input only goes to one output.
6. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.
7. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.
8. is a function because each input only goes to one output. It also passes the vertical line test.
9. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.
10. is a function because each input only goes to one output. It also passes the vertical line test.
11. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.
12. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.
Hope this helps!
Answer:
Step-by-step explanation:
5z >or= -75
z >or= -75/5
z>or= -15
ans is D
Answer:
1/20 because it has no effect so it would always be the smallest fraction
Step-by-step explanation:
Answer:
There are 52 such numbers that have even divisors.
Step-by-step explanation:
All the numbers between 2 and 59 have an EVEN number of positive divisors.
Except the Perfect Squares..
or 4, 9, 16, 25, 36 and 49, which have 3 divisors each.
So:
59 - 2 + 1 =58
Now subtract 58 from 6 (perfect squares)
58- 6=52
Therefore,it means that there are 52 such numbers that have EVEN divisors....
The answer is b because all you have to do is just subtract if I am wrong so sorry
