9. which set of output values correctly completes the function table?
y=6-x
input (X) output (y)
-2 ?
-1 ?
3 ?
-----------------------
4,5,3
-8,-7,3
8,7,3
11. What is the function rule shown by the table?
input(x) output(y)
-2 -3
0 1
1 3
2 5
---------------------
y=x-1
y=x+2
y=2x+1
what the hell are the answers
My goodness, it would be so easy to just plug in the 3 given values.
For the 2nd, just looking at the last 3 cases, for each increase of 1 in the x, we get an increase of 2 in the y, so ...... I only see one equation that says that.
I need answers
To complete the function table, we can substitute the given input values into the function y = 6 - x and calculate the corresponding output values.
For the first input value of -2, we can substitute it into the function:
y = 6 - (-2) = 6 + 2 = 8
For the second input value of -1, we substitute it into the function:
y = 6 - (-1) = 6 + 1 = 7
For the third input value of 3, we substitute it into the function:
y = 6 - 3 = 3
Therefore, the correct set of output values to complete the function table is:
-8, -7, 3
Now, let's move on to the next question:
To determine the function rule shown by the table, we need to compare the input and output values and observe the relationship.
From the given table, we can see that the output (y) is equal to the input (x) minus 1. For example, when x is -2, y is -3. When x is 0, y is 1. When x is 1, y is 3. When x is 2, y is 5. The output value (y) is always one less than the input value (x).
Therefore, the correct function rule shown by the table is:
y = x - 1
9.
6 - -2 = 8
6 - -1 = 7
6 - +3 = 3

hint
2*-2 + 1 = -3
2*0 + 1 = 1
2*1 + 1 = 3
