Question 531246: The function f is one-to-one, find its inverse and determine the domain and range of both f and f^-1.
f(x)=radical sign 19-x Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! The function f is one-to-one, find its inverse and determine the domain and range of both f and f^-1.
f(x)=radical sign 19-x
Find f^1(x):
y = 19-x
Interchange x and y to get:
x = 19-y
Solve for "y":
y = 19-x
So, f^-1(x) = 19-x
--------
Domain and Range of both are "All Real Numbers".
