Question

Just before the morning assembly a teacher of kindergarten school observes some clouds in the sky and so she cancels the assembly. She also observes that the clouds has a shape of the polynomial. The mathematical representation of a cloud is shown in the figure.

(i) Find the zeroes of the polynomial represented by the graph.
(a) -1/2,7/2 (b) 1/2, -7/2 (c) -1/2, -7/2 (d) 1/2,7/2

(ii) What will be the expression for the polynomial represented by the graph?
(a)p(x)=12xˆ2−4x−7 (b)p(x)=−xˆ2−12x+3 (c)p(x)=4xˆ2+12x+7 (d)p(x)=−4xˆ2−12x+7

(iii) What will be the value of polynomial represented by the graph, when x = 3?
(a) 65 (b) -65 (c) 68 (d) -68

(iv) If a and β are the zeroes of the polynomial f(x)=x2+2x−8 , then α4+β4=
(a) 262 (b) 252 (c) 272 (d) 282

(v) Find a quadratic polynomial where sum and product of its zeroes are 0,(√7) respectively.
(a)k(x2+√7) (b)k(x2−√7) (c)k(x2+√5) (d) none of these​
