Answer:

  [tex]F^{-1}(x)=\dfrac{x-7}{4}[/tex]

Step-by-step explanation:

To find the inverse function, solve for y the relation ...

  F(y) = x

  4y +7 = x

  4y = x - 7

  y = (x -7)/4 . . . . the inverse function

  [tex]\boxed{F^{-1}(x)=\dfrac{x-7}{4}}[/tex]

Answer: B

4x+7=y

Subtract 7 from both sides

4x=y-7

Divide both sides by 4

x= (y-7)/4

Switch x and y

y= (x-7)/4

So the answer is B
