Q. Find a formula for the inverse of the following function, if possible.G(x)=54x+2
Understand Goal: Understand the function and the goal.We are given the function G(x)=54x+2, and we need to find its inverse. The inverse function will take the output of G and return the input x.
Set Equation Equal: Set G(x) equal to y for convenience.Let y=G(x), so we have y=54x+2.
Swap x and y: Swap x and y to begin finding the inverse.To find the inverse, we switch the roles of x and y. This gives us x=54y+2.
Isolate y Term: Isolate the term containing y. To solve for y, we need to get rid of the fifth root. We do this by raising both sides of the equation to the power of 5. This gives us x5=(54y+2)5.
Simplify Equation: Simplify the equation.When we raise the fifth root to the power of 5, they cancel each other out, leaving us with x5=4y+2.
Solve for y: Solve for y.Now we need to isolate y. We do this by subtracting 2 from both sides and then dividing by 4. This gives us (x5−2)/4=y.
Write Inverse Function: Write the inverse function.The inverse function, which we can denote as G−1(x), is then G−1(x)=4x5−2.
