explain How to write a function rule from the table below. Then write a funciton rule.

Question

X|Y
0|2
2|1
4|0
6|-1

Answer 1

To write a function rule, we need to identify the relationship between the input values (X) and the output values (Y). Looking at the table, we notice that as X increases by 2, Y decreases by 1. This tells us that the function is a linear function with a slope of -1/2.

Therefore, the function rule can be written as:

Y = -1/2 X + 2
