Answer:
i dont knwo
Step-by-step explanation:
Answer:
In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.
Step-by-step explanation:
Requirement to be a function:
For a relationship to be a function, all values of x must have only one corresponding value of y.
In this question:
For x = -7, y = 2
For x = -1, y = 0
For x = 4, y = 0
For x = k, y = 0
A value of x must not have more than 1 value of y.
In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.
