Let f:RtoR:f(x)=x^(2)" for all "x""inR.

Answer»

Solution :Here, `F:RtoR:f(x)=x^(2)" for all "x""INR`
Dom (f)=R and range `(f)={x""inR:ge0}=[0,OO)`.
Now, we have:

On a graph paper, we draw X' OX and YOY' as the x-axis and the y-axis respectively.
Now, we plot the points A(-2,4), B(-1.5), C(-1.1), O(0,0), D(1,1), E(1.5,2.25) and F(2,4).
Join these points freehand successively to obtain the required curve.
