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

eg. f(x) + 7

put x = 0 and x = 2 to work out the new range.

Not sure what you mean by graph.

Hi Bob

How do you know which values f(x) takes at x=0 and x=0 when it os nowhere explicitly given?

Good point. I'm assuming f is linear.

It could be a polynomial of degree 100 for all you know...
