Question

Help i dont know whats the answer

Answer 1

A.
`p(x)=7x-2`

Explanation:

Given function:

`y=(x+2)/(7)`

Rearrange to make x the subject:

`\implies 7y=x+2`

`\implies x=7y-2`

Swap x and y:

`\implies y=7x-2`

This is the inverse of the original function.

Therefore, the answer is A
`p(x)=7x-2`
