Function or no function 12 questions Don't put childish stuff I will report

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!

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
