I have f(x)= x-2 square
this is the symbolic form I have to make a table and graph it . How do I do this and what number do I start with

Question

radar · Answer

Is it$$f(x)=(x-2)^{2}$$ or
$$f(x)=x-2^{2}$$ I am going to assume it was the first rather than the latter.

anonymous · Answer

f(x)=$$\sqrt{x-2?}$$

anonymous · Answer

is X=-4

(ok) I was wrong on both counts lol.

For the graph i would use x at values of -2. -1, 0, 1, 2
x                       f(x)
-2                     2i  Complex number
-1                     sq root of -3 again a complex value
0                       sq root of -2 complex
1                       sq root of -1 or i
2                       0
 3                       1
4                       sq root 2= 1.414 
5                        sq root 3= 1.73
6                        2

that should allow you to start the graph.

I don't think you can get a single solution with the info you have.  Sorry but I got to run, will check later.

THANK YOU

You could say f(x) has real roots when$$x \ge2$$
