Due to heavy storm an electric wire got bent as shown in the figure. It followed a mathematical
shape. Answer the following questions below.
(a) Name the shape in which the wire is bent.
(i)Parabola (ii)Hyperbola (iii)Ellipse (iv)Spiral
(b) If the parabola has the expression as p(x) = x² - 2x - 3 , then the
zeroes of this polynomial are
(i)-1, 5 (ii)-1, 3 (iii)3, 5 (iv)-4, 2
(c) How many zeroes are there for the polynomial : p(x) = x + 1?
(i)2 (ii)3 (iii)1 (iv)0
(d) The factors of the polynomial x² - 2x - 3 are
(i) (x + 1)(x + 3) (ii) (x - 1)(x + 3)
(iii) ( x + 1)(x - 3) (iv) (x - 1)(x - 3)
(e) What is the value of the polynomial( formed by the parabola) at x = -1?
(i)6 (ii) -18 (iii) 18 (iv) 0
