Question

Rewrite x - 2y = 8 using function notation.

Answer 1

-2y= -x+8
so it is your answer
y=1/2x -4

Answer 2

Function nation:
`f(x) = (x-8)/(2)`

Explanation:

We are given the expression:

`x - 2y =8`

We have to write it in the function notation.

We follow the following steps:

`x - 2y =8\\2y = x - 8\\\\y = \displaystyle(x-8)/(2)\\\\f(x) = y = (x-8)/(2) = (x)/(2)-4`

Thus, the function nation is
`f(x) = (x-8)/(2)`
