Answer:
y = x -2
Step-by-step explanation:
The simplest function rule that will match the two given inputs and outputs is a linear function. We see that the output changes by -1-(-4) = 3 when the input changes by 1-(-2) = 3, so the slope is 3/3 = 1.
The output is 2 less than the input for both of the given table values, so we can write the rule as ...
y = x - 2
The table will look like the one attached. (Given value pairs are highlighted.)
