Rule for Input-Output

Question:

by Emone Vinson
(Houston, Tx)

Which rule can be used to represent the relationship between input and output as shown in this table?


Input (x) Output (y)
0 -2
1 -1
2 0
3 1



Answer:

The input-output rule for the relationship between x and y for the table of values shown is:

y = x - 2

-----------------------------------------------
check the input-output rule:


if x is 0, what is y ?

y = x - 2

y = 0 - 2

y = -2

if x = 0, y = -2: these x-y values match row 1 of the table


if x is 1, what is y ?

y = x - 2

y = 1 - 2

y = -1

if x = 1, y = -1: these x-y values match row 2 of the table


if x is 2, what is y ?

y = x - 2

y = 2 - 2

y = 0

if x = 2, y = 0: these x-y values match row 3 of the table


if x is 3, what is y ?

y = x - 2

y = 3 - 2

y = 1

if x = 3, y = 1: these x-y values match row 4 of the table



Thanks for writing.
