identify the function rule from the values in the table input; -1,0,1,2 output; -2,-1,0,1
output equals input times 2
output equals input minus 1
output equals input times -1
output equals input minus 2
your calculations are correct, but that is not C
so what are the answers can you pleas give the answers
B
Yes, the correct answer is B) output equals input minus 1.
To identify the function rule from the given table, we can look for patterns between the input values and the corresponding output values.
In this case, the input values are -1, 0, 1, and 2, and the output values are -2, -1, 0, and 1.
By observing the relationship between the input and output values, we can determine the function rule.
Let's analyze the options one by one:
1. Output equals input times 2:
- For the input value -1, the output is -2, which is not equal to -1 times 2.
- For the input value 0, the output is -1, which is not equal to 0 times 2.
- For the input value 1, the output is 0, which is not equal to 1 times 2.
- For the input value 2, the output is 1, which is not equal to 2 times 2.
Therefore, this option does not hold true for all values in the table.
2. Output equals input minus 1:
- For the input value -1, the output is -2, which is equal to -1 minus 1.
- For the input value 0, the output is -1, which is equal to 0 minus 1.
- For the input value 1, the output is 0, which is equal to 1 minus 1.
- For the input value 2, the output is 1, which is equal to 2 minus 1.
Therefore, this option holds true for all values in the table, making it the correct function rule.
3. Output equals input times -1:
- For the input value -1, the output is 1, which is not equal to -1 times -1.
- For the input value 0, the output is 0, which is not equal to 0 times -1.
- For the input value 1, the output is -1, which is not equal to 1 times -1.
- For the input value 2, the output is -2, which is not equal to 2 times -1.
Therefore, this option does not hold true for all values in the table.
4. Output equals input minus 2:
- For the input value -1, the output is -3, which is not equal to -1 minus 2.
- For the input value 0, the output is -2, which is equal to 0 minus 2.
- For the input value 1, the output is -1, which is not equal to 1 minus 2.
- For the input value 2, the output is 0, which is not equal to 2 minus 2.
Therefore, this option does not hold true for all values in the table.
After analyzing all the options, we can conclude that the correct function rule is:
- Output equals input minus 1.
I picked c
Your answer is correct.
Input , Output
- 1 - 1 = - 2
0 - 1 = - 1
1 - 1 = 0
2 - 1 = 1
