If f(x) = 7 x +12, what is f-1(x) (the inverse function)?

• let y = f(x) = 7x + 12
  => 7x = y-12
  => x = (y-12)/7
  => f-1(x) = (x-12)/7

• Inverse is (x-12)/7
• 9 years agoHelpfull: Yes(1) No(0)
• f(x)=7x+12
  let y=7x+12
  
  so x=y-12/7
  So the req inverse function is f^-1(x)=x-12/7

• y=7x+12
  x=(y-12)/7
  f-1(x)=x-12/7

• f(x)=7x+12
  y=7x+12
  x=y-12/7
  inverse f(x)=(x-12)/7

• a=7x+12
  find the value of x
  x=a-12/7
  change the constants
  ans=x-12/7

• f inverse =(x=X-12/7)
• 9 years agoHelpfull: Yes(0) No(1)
• f inv(x)=(x-12)/7
• 9 years agoHelpfull: Yes(0) No(0)
• suppose y=f(x)
  so,
  y=7x+12
  x=(y-12)/7
  so f-1(x)=(x-12)/7
