Q. What is the inverse of the function \newlineg(x)=5(x2)?g(x)=5(x-2) ?\newlineg1(x)=g^{-1}(x)=
  1. Concept of Inverse Function: Understand the concept of an inverse function.\newlineThe inverse function g1(x)g^{-1}(x) will undo the operation done by g(x)g(x). To find the inverse, we need to solve for xx in terms of yy where y=g(x)y = g(x).
  2. Writing the Function as an Equation: Write the function g(x)g(x) as an equation with yy.\newlineLet y=g(x)y = g(x), so we have y=5(x2)y = 5(x - 2).
  3. Swapping xx and yy: Swap xx and yy to begin finding the inverse function.\newlineWe replace yy with xx and xx with yy to get x=5(y2)x = 5(y - 2).
  4. Solving for y: Solve for y to find the inverse function.\newlineWe need to isolate y on one side of the equation. Start by dividing both sides by 55.\newlinex5=y2\frac{x}{5} = y - 2
  5. Writing the Inverse Function: Continue solving for yy.\newlineAdd 22 to both sides of the equation to isolate yy.\newlinex5+2=y\frac{x}{5} + 2 = y
  6. Writing the Inverse Function: Continue solving for yy.\newlineAdd 22 to both sides of the equation to isolate yy.\newlinex5+2=y\frac{x}{5} + 2 = y Write the inverse function.\newlineNow that we have yy by itself, we can write the inverse function as g1(x)=x5+2g^{-1}(x) = \frac{x}{5} + 2.
