Nction rule given a table of ordered pairs: Two-step rules
A table of values of a linear function is shown below. Find the output whe
input 1
2
3
4
output -5 -7 -9 - 11
n
N
0+0
OXO
3.
To find the output when the input is 3, we can use the given table of ordered pairs.
We can observe that the output values decrease by 2 each time the input increases by 1. This suggests that the function rule follows a two-step pattern: subtracting 2 from the input and then multiplying it by -2.
To find the output when the input is 3, we can apply this two-step pattern.
First, we subtract 2 from the input: 3 - 2 = 1.
Next, we multiply the result by -2: 1 * -2 = -2.
Therefore, the output when the input is 3 is -2.
