Question 27932: Graph f(x)=/x+2/. Note that f(x) is not one to one. Restrict the domain of f(x) so that it does not have an inverse
Answer by longjonsilver(2297)   (Show Source):
You can put this solution on YOUR website! plot y=x+2 for x>= -2...a straight line
The portion of y=x+2 below x=-2 is mirrored in the x-axis, creating a V-shaped graph. Algebraically, you are plotting y=-(x+2).
I think you mean restrict the domain of f(x) so that it DOES have an inverse.
Domain could be all values of x, so long as x>=-2. Or the domain could be all values of x, so long as x<= -2.
Either set of x-values is a valid domain for the function.
