प्रश्न
If f(x) is a polynomial such that f(a) f(b) < 0, then what is the number of zeros lying between a and b?
उत्तर
If f (x) is a polynomial such that `f(a) f (b) < 0` then this means the value of the polynomial are of different sign for a to b
Hence, at least one zero will be lying between a and b

An asana is a body posture, originally and still a general term for a sitting meditation pose, and later extended in hatha yoga and modern yoga as exercise, to any type of pose or position, adding reclining, standing, inverted, twisting, and balancing poses. In the figure, one can observe that poses can be related to representation of quadratic polynomial.

Basketball and soccer are played with a spherical ball. Even though an athlete dribbles the ball in both sports, a basketball player uses his hands and a soccer player uses his feet. Usually, soccer is played outdoors on a large field and basketball is played indoor on a court made out of wood. The projectile (path traced) of soccer ball and basketball are in the form of parabola representing quadratic polynomial.
