Q. For the function f(x)=6x7−4, find f−1(x).f−1(x)=67x+4f−1(x)=76x+4f−1(x)=76x+4f−1(x)=67x+4
Define Original Function: To find the inverse function, f−1(x), we need to switch the roles of x and y in the original function and then solve for y. The original function is f(x)=6x7−4, which we can write as y=6x7−4.
Replace y with x: Replace y with x to begin finding the inverse function: x=6y7−4.
Isolate y term: Add 4 to both sides of the equation to isolate the term containing y: x+4=6y7.
Divide by 6: Divide both sides of the equation by 6 to further isolate the y term: (x+4)/6=y7.
Take 7th root: Take the 7th root of both sides of the equation to solve for y: y=76x+4.
Express Inverse Function: Replace y with f−1(x) to express the inverse function: f−1(x)=76x+4.
