Answer:
B. The second choice.
Step-by-step explanation:
A function cannot have two points with the same x-coordinate.
If you graph two different points that have the same x-coordinate, they will both lie on the same vertical line. Therefore, if in a relation, more than one point lie on the same vertical line, then the relation is not a function.
Answer: B
Step-by-step explanation:
A is incorrect because going from -10 to 10 is not 0, it is 20.
C is incorrect because 21 km from sea level is adding 21.

- -2
- -1
- -0.5
- 3/2
- 4 3/4
the biggest negative number should be last and the biggest whole number should be last
The inverse....switch ur x's and y's...
inverse :
domain is { -2,2,4,4,5} ...notice u have 2 "x" values that are 4
range is {-3,0,2,3,4}
The relation DOES NOT represent a function. A function will not have any repeating x values. It can have repeating y values, just not the x ones.
Now the relation would be a function...but the inverse is not
