Question

Draw the graph of
$2x$ and find the point of intersection on X - axis. Is the zeroes of the polynomial?

Answer 1

Let $y=2x$
When $x=0$
$y=2\times 0=0$
When $x=-1$
$y=2\times -1=-2$
When $x=1$
$y=2\times 1=2$
List of $x$ and $y$
$x0-11$
$y0-22$
$(x,y)=(0,0),(-1,-2),\left(\right(1,2)$
$\therefore$ The graph $y=2x$ passes through the origin $(0,0)$.
$\therefore$The zeroes of the polynomial is zero.
