Question

18. A student was given the task to prepare a graph
of quadratic polynomialſ(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
f(x)
(0, 1)
(3.0)
(1.0)

2Based on the above graph, answer the following questions:


(i) The graph of quadratic polynomial intersects
X-axis :
(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
x-coordinates of those points :
(a) where their graph touch or intersect the
X-axis.
(b) where their graph touch or intersect the Y-axis.
(c) where their graph touch or intersect both
axes.
(d) none of these


(iii) The sum of zeroes of the polynomial f(x) is:
(a) 1
(b) 2
(c) 3
(d) 4


(iv) The product of zeroes of the polynomial f(x) is:
(a) 1
(b) 2.
(C) 3
(d) 4


(v) What will be the expression of Polynomial
f(x)?
(a) x2 - 4x +3
(c) x2 + 4x - 3
(d) x2 + 3x - 4
(b) x2 - 3x + 4​
