Answers
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
What will be the expression of the polynomial shown in the figure
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
(c) Intersects at y-axis or x-axis (d) None of the above
(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
the expression of the polynomial shown in the figure will be
y=ax² + bx + c
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
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
