Select the correct answer.
Which function is the inverse of function
f(x) = -2

B

Step-by-step explanation:

let f(x) = y and rearrange making x the subject

y = ( multiply both sides by 7 to clear the fraction )

7y = x + 2 ( subtract 2 from both sides )

7y - 2 = x

Change y back into terms of x with x the inverse function, that is

p(x) = 7x - 2
