Identify the following expression is polynomial. If not give reason:
`1/x^2 + 3x - 4`
उत्तर
`1/x^2 + 3x - 4` is not a polynomial.
Since the exponent of x2 is not a whole number, but it is `(1/x^2 = x^(-2))` negative number.

The figure given alongside shows the path of a diver, when she takes a jump from the diving board. Clearly it is a parabola.
Annie was standing on a diving board, 48 feet above the water level. She took a dive into the pool. Her height (in feet) above the water level at any time‘t’ in seconds is given by the polynomial h(t) such that h(t) = -16t2 + 8t + k.
At what time will she touch the water in the pool?
The below picture are few natural examples of parabolic shape which is represented by a quadratic polynomial. A parabolic arch is an arch in the shape of a parabola. In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms.
