Answer: the first set of data:
Input x -3 -2 -1 0 1
Output y -1 0 1 2 3
Explanation:
Given functión y = x + 2
Choices:
1)
Input x -3 -2 -1 0 1
Output y -1 0 1 2 3
2)
Input x 3 4 5 6 7
Output y 5 7 9 11 13
Answer:
You just have to use the sets of input values and find the output values with the given function:
The computes are very simple so you can tell the answer at first sight, because the output, y, is 2 units more than the input, x.
The first set of data fits the function because
x = -3 => y = -3 + 2 = -1
x = -2 => y = -2 + 2 = 0
x = -1 => y = -1 + 2 = 1
x = 0 => y = = 0 + 2 = 2
x = 1 => y = 1 + 2 = 3
That proves that the first set of data represents the given rule.
For the second set of data pick x = 4 => x + 2 = 6 but the correspondant y is 7, so that set does not represent the rule y = x + 2
