Question

Draw a graph of $y=x^2;x,y\in R$

Answer 1

Assign the values for $x$ from $-5$ to $5$ and we get the corresponding $y$ values.Then tabulate as follows:

$x$	$-5$	$-4$	$-3$	$-2$	$-1$	$0$	$1$	$2$	$3$	$4$	$5$
$y$	$25$	$16$	$9$	$4$	$1$	$0$	$1$	$4$	$9$	$16$	$25$

Plot the points $(-5,25),(-4,16),(-3,9),(-2,4),(-1,1),(0,0),(1,1),(2,4),(3,9),(4,16),(5,25),$ on the graph sheet and join the points by a smooth curve.This curve is called parabola.
