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

Good point. I'm assuming f is linear.Bob

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

eg. f(x) + 7put x = 0 and x = 2 to work out the new range.Not sure what you mean by graph.Bob

domain and range sorry and a graph.

Did you mean the range ?Bob

domain of a figure is [0,2]range is [0,1]How do I find the domain for f(x)+7f(x)-73f(x)-f(x)f(x+1)f(x-1)f(-x)-f(x+1)+1
