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. 1) The graph of the parabola opens upwards, if _______. (a) a = 0 (b) a < 0 (c) a > 0 (d) a ≥ 0 2) Observe the following graph and answer. In the above graph how many zeroes are there for the polynomial ? (a) 0 (b) 1 (c) 2 (d) 3 3) The three zeroes in the above shown graph are (a) 2, 3, -1 (b) -2, 3, 1 (c) -3, -1, 2 (d) -2, -3, -1 4) What will be the expression of the polynomial (a) x³ + 2x² - 5x - 6 (b) x³ + 2x² - 5x + 6 (c) x³ + 2x² + 5x - 6 (d) x³ + 2x² + 5x + 6
