f(x) = x[edit | edit source]
Let f(x)=y . Then the value of y for all x are
x: -3 -2 -1 0 1 2 3 y: -3 -2 -1 0 1 2 3
- Plot these x,y gives a graph of a straight line which has positive slope of 1 that pass through origin at (0,0)
f(x) = -x[edit | edit source]
Let f(x)=y . Then the value of y for all x are
x: -3 -2 -1 0 1 2 3 y: 3 2 1 0 1 2 3
- Plot these x,y gives a graph of a straight line which has negative slope of 1 that pass through origin at (0,0)
