$Q^{19}$ A student was given the task to prepare a graph
of quadratic polynomial $f\left(x\right).T0$ draw this graph he
take several values of y corresponding to different
values of x. After plotting the points on the graph
paper with suitable $scae$ he obtain the graph as
shown below
$y=f\left(x\right)$ 43

Based on the above graph, answer the following
$9uestions$
(i) The graph of quadratic polynomial intersects
$xa\times i5$ :
(a) atleast at two points (b) atmost at two points
(c) exactly one point (d) none of these.
(ii) The zeroes of the polynomial are the
$xcoordinates$ of those points:
(a) where their graph touch or intersect the
$xaxis$
(b) where their graph touch or intersect the $yaxi5$
Scanned by T
(c) where their graph touch or intersect both
axes.
(iii) T(dh) e none of these.
sum of zeroes of the polynomial $f\left(x\right)is$
(a) 1 (b) 2
3 $\left(d\right)4$
(iv) T(hc) e product of zeroes of the polynomial $f\left(x\right)lsi$
$\left(b\right)2$ $\left(d\right)$ $4$
$omia1$
(v) AW(((acaXh) ) ) )a? 3 1 t will be the expression of Polynomial

$x^{2}4x+3$ $x^{2}+4x3$ (b) $x^{2}3x+4$ $x^{2}+3x4$
