Question

Q18. A student was given the task to prepare a graph of quadratic polynomial f(x). To 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 scale, he obtain the graph as shown
below:-
y fod
3-
2
1 101)
\10)
13.0)
Based on the above graph answer the following questions :-
The graph of quadratic polynomial intersects X-axis :-
(a) at least at two points
(b) atmost at two points
(c) exactly one point
(d) none of these
The zeroes of the polynomial are the x-coordinates of those points :-
(ay where their graph touch or intersect the X-axis.
(b) where their graph touch or intersect the Y=axis.
where their graph touch or intersect both axs,
d)
none of these​
