Answer:
Table 3
Explanation:
For a relation to be a function, each x value should have only one corresponding y value.
Now, let's check the givens:
Table 1:
x = 1 has two corresponding y-values. Therefore, this is not a function
Table 2:
x = 10 has two corresponding y-values. Therefore, this is not a function.
Table 3:
each x value has only one corresponding y-value. Therefore, this one is a function
Table 4:
x = 7 has two corresponding y-values. Therefore, this is not a function.
Hope this helps :)
