domain and range
domain of a figure is [0,2]
range is [0,1]
How do I find the domain for f(x)+7
f(x)-7
3f(x)
-f(x)
f(x+1)
f(x-1)
f(-x)
-f(x+1)+1

Re: domain and range
Hi Bob
How do you know which values f(x) takes at x=0 and x=0 when it os nowhere explicitly given?
The limit operator is just an excuse for doing something you know you can't.

Re: domain and range
It could be a polynomial of degree 100 for all you know...
