Q. What is the inverse of the function\newlineg(x)=2(x4)?g(x)=-2(x-4)?\newlineg1(x)=g^{-1}(x)=
  1. Replace g(x)g(x) with yy: To find the inverse of the function g(x)=2(x4)g(x) = -2(x - 4), we first replace g(x)g(x) with yy to make the equation easier to manipulate. So we have y=2(x4)y = -2(x - 4).
  2. Swap xx and yy: Next, we swap xx and yy to find the inverse. This gives us x=2(y4)x = -2(y - 4).
  3. Solve for y: Now, we solve for y. Start by dividing both sides by 2-2 to isolate the term with y. This gives us x2=y4\frac{x}{-2} = y - 4.
  4. Add 44 to both sides: Next, add 44 to both sides to solve for yy. This gives us y=x2+4y = \frac{x}{-2} + 4.
  5. Inverse function expression: The expression we have now represents the inverse function. So, g1(x)=x2+4g^{-1}(x) = \frac{x}{-2} + 4.
