solve the following function and sketch the coordinates on a graph... f(x)=-x x

Question

solve the following function and sketch the coordinates on a graph...
f(x)=-x     x<0
         x^2   0<x<1(o is less than or equal to x and x is less than or equal to 1) 
         1         x>1
plz help....:(

mimi, solving the function doesn't make any sense here. But of course you can sketch the graph of f(x). Look at this video to understand how to sketch the graph of a piecewise function http://www.youtube.com/watch?v=9aXoOhNK_-s&feature=fvsr

we put x=0 in -x after then (0,0) coordinates come 
same is the case with others

Yep, that's a piecewise function. It just means that you apply different rules according to the constraints. For instance, in your function, if you have x=-2, then you apply the rule corresponding to x<0, which is -x. So the f(x) there would be -(-2)=2

Google piecewise function.

plz help me with the 2nd one
which is x^2    0<x<1      
0 is less than or equal to x and x is less than or equal to 1

anonymous · Answer

x^2, 0<x<1
What about it? What x do you have to find?
