2021年7月30日 · Verifying inverse functions from tables. Worked example: Continuity at a point (graphical) Worked example: point where a function is continuous. Worked example: point where a function isn't continuous. Worked example: using the intermediate value theorem. Working with matrices as transformations of the plane

Yes, f(x) = 2x/(x^2-1) is not invertible. But restricting it's domain to (-1,1) would allow us to conclude that the inverse of the function f is 1/y.(1 - sqrt(1+x^2)) and the graph of the same is as below. Now, f-inverse(x) = 1/x.[1-sqrt(x^2+1)] and f(x) = 2x/(x^2-1) for (-1 < x < 1). f-inverse is now a completely valid function, and (f-inverse ...

Determine an inverse function, when it exists, for a given function over its domain or a subset of its domain and represent the inverse using multiple representations.
