Seema is studying in class X. She visited Metro station several times. One day she has noticed the
roof of the Metro Station. She observed that this is a Mathematical shape, she has learned in Maths
class. On reaching home, Seema draw the following graph of the figure:
(i) Seema shows the roof of metro in which shape ?
a) Spiral b) Ellipse c) Linear d) Parabola
(ii) How many zeroes are possible for this shape ?
a) 2 b) 3 c) 1 d) 0
(iii) According to graph, the zeroes of the polynomial are:
a) -2,2 b) 0, 2 c) 2,0 d) 0,0
(iv) What will be the expression of the polynomial?
a) x2
-4x+4 b) - x2
-4x+4 c) x2
+4x+4 d) x2
–4
(v) What is the value of the polynomial if x = 1?
a) -1 b) 3 c) -3 d) 1
Answers
Answer:
sorry I don't know the answer keys make me
Solution :-
(i) Shape of the roof of the metro station is (d) Parabola .
(ii)
→ Possible zeros for given shape are = where graph cuts at x - axis = (-2 , 2) = Total 2 (a)
(iii)
→ The zeroes of the polynomial are = (-2, 2) (a)
(iv)
→ Expression of the polynomial = x² - (sum of zeros)x + product of zeros = x² - (-2 + 2)x + (-2) * 2 = x² - 0x - 4 = x² - 4 (d)
(v)
→ Value of polynomial at x = 1 is = x² - 4 = (1)² - 4 = 1 - 4 = (-3) (c)
