Q. What is the inverse of the function \newlinef(x)=6x7 f(x) = -6x - 7 ?\newlinef1(x)= f^{-1}(x) =
  1. Replace f(x)f(x) with yy: To find the inverse of the function f(x)=6x7f(x) = -6x - 7, we first replace f(x)f(x) with yy. So, we have y=6x7y = -6x - 7.
  2. Swap xx and yy: Next, we swap xx and yy to find the inverse. This gives us x=6y7x = -6y - 7.
  3. Solve for y: Now, we solve for y. We start by adding 77 to both sides of the equation to isolate the term with yy. This gives us x+7=6yx + 7 = -6y.
  4. Divide both sides by 6 -6 : Next, we divide both sides of the equation by 6 -6 to solve for y y . This gives us y=x+76 y = \frac{x + 7}{-6} .
  5. Write the inverse function: The inverse function is then written as f1(x)=x+76f^{-1}(x) = \frac{x + 7}{-6}.
