Answer:
A. [tex]p(x)=7x-2[/tex]
Step-by-step explanation:
Given function:
[tex]y=\dfrac{x+2}{7}[/tex]
Rearrange to make x the subject:
[tex]\implies 7y=x+2[/tex]
[tex]\implies x=7y-2[/tex]
Swap x and y:
[tex]\implies y=7x-2[/tex]
This is the inverse of the original function.
Therefore, the answer is A [tex]p(x)=7x-2[/tex]
