300
This word describes a relation that pairs each x value with only one y value.
A function
300
Is this a function and why?
No because x=8 has two outputs (3 and -3)
300
Evaluate y = x2 - 2 when x = -2
y = 2

Does the following table represent a function?
x y
1 2
2 5
6 2
2 9
5 1
No, because the input (x) of 2 has two different outputs (y)
