Question

explain how to write a function rule from the table below. then write the function rule.

x 2 4 6
y 1 0 -1

Answer 1

The question is asking for A function not THE function. So any function that satisfies those values will work.
So,
f(2)=1f(4)=0f(6)=−1

Where f(x) is the "rule," which we can call a function.
Here is our function
f=⎧⎩⎨⎪⎪10−1 for x = 2 for x = 4 for x = -1

This is one way to implement this rule.

Answer 2

*Correction on function
f=⎧⎩⎨⎪⎪10−1 for x = 2 for x = 4 for x = 6
