Q. What is the inverse of the function g(x)=5(x−2)?g−1(x)=
Concept of Inverse Function: Understand the concept of an inverse function.The inverse function g−1(x) will undo the operation done by g(x). To find the inverse, we need to solve for x in terms of y where y=g(x).
Writing the Function as an Equation: Write the function g(x) as an equation with y.Let y=g(x), so we have y=5(x−2).
Swapping x and y: Swap x and y to begin finding the inverse function.We replace y with x and x with y to get x=5(y−2).
Solving for y: Solve for y to find the inverse function.We need to isolate y on one side of the equation. Start by dividing both sides by 5.5x=y−2
Writing the Inverse Function: Continue solving for y.Add 2 to both sides of the equation to isolate y.5x+2=y
Writing the Inverse Function: Continue solving for y.Add 2 to both sides of the equation to isolate y.5x+2=y Write the inverse function.Now that we have y by itself, we can write the inverse function as g−1(x)=5x+2.
