Given : The figure shows a bridge with hanging wires showing a mathematical shape

To Find :

Name the shape of the hanging wire

(a) Linear (b) Spiral (c) Parabola (d) None of the these

The hanging wires on the bridge is represented graphically. Zeroes of a polynomial can be expressed graphically. Number of zeroes of polynomial is equal to number of points where the graph of polynomial.

(a) intersects at x-axis (b) Intersects y-axis

(iii) The representation of Hanging wires on the bridge whose sum of the zeroes is -3 and product of the zeroes is 5 is

Solution :

Name the shape of the hanging wire is Parabola

intersects at x-axis

The representation of Hanging wires on the bridge whose sum of the zeroes is -3 and product of the zeroes is 5 is

x² -(-3x) + 5

= x² + 3x + 5
